Rounding off the Playhouse Presents... series, this five-part comedy sketch show makes itself comfortable on the couch for a witty variation on the therapist theme of HBO's In Treatment. Rebecca Front anchors the action as a long-suffering psychoanalyst whose appointment diary is lit up by a galaxy of stars from yesteryear, as played by some of today's finest acting talent. Stand-out headcases include Frances Barber and Mark Gatiss as Bette Davis and Joan Crawford (in Whatever Happened To Baby Jane mode), Sam Spiro (Grandma's House) as irrepressibly cutesy Audrey Hepburn and Julia Davis (Hunderby) conjuring comedic magic by mixing poet Sylvia Plath's tragic angst with the simple jollity of Pam Ayres.

After a promising pilot last year, this fitfully funny set of vignettes based around famous women visiting a therapist (Rebecca Front) returns as a series. Boasting comedic talent such as Sharon Horgan, Samantha Spiro, Julia Davis, Katy Brand and Mark Gatiss - dragged up as Joan Crawford - it's a riot when it does very silly: Sylvia Plath channelling Pam Ayres in an attempt to lift her dark moods; the squabbling, doll-sized Brontë sisters, and Jacqueline du Pré communicating only via cello.

This Playhouse Presents... production from last year returns for a series, boasting the same strengths and weaknesses as its pilot. It's undeniably pretty slight - the single, running gag is seeing absurdly exaggerated caricatures of famous historical women visit Rebecca Front's modern shrink and flaunt their entertaining neuroses. But the joke is carried through with enough conviction and élan to make it pretty entertaining.

Tonight's highlight is Julia Davis's turn as Sylvia Plath - but a Sylvia Plath who, concerned that her creativity might be compromising her mental health, is considering adopting the poetry stylings of Pam Ayres. Elsewhere, there are foul-mouthed Brontë sisters, an infuriating Audrey Hepburn and the endless bitching of Bette Midler and Joan Crawford. The cast is excellent - Davis, Front and Sharon Horgan are now augmented by Frances Barber and Mark Gatiss - and they're clearly enjoying themselves too. Good fun.

You can't libel the dead, which will be great comfort to Sky's lawyers as the Playhouse pilot from last year is expanded into a complete series.

Rebecca Front stars as a ­psychotherapist with a patient roster that reads like a Who's Who of famous women from history.

This show totally undermines the feminist message of the BBC's Up The Women, which Front also stars in, by depicting all females of achievement as neurotic loons. Still, one thing women have always been good at is laughing at themselves. I hope.

The make-up and wardrobe departments really excel ­themselves here. The joke works even before Bette Davis and Joan Crawford (Frances Barber and Mark Gatiss) open their mouths.

The squabbling Bronte sisters are brilliant, just as Samantha Spiro makes for a ­wonderfully convincing Audrey Hepburn.

And Sylvia Plath (Julia Davis) doing a Pam Ayres in an attempt to rid herself of demons is inspired. This must also be the first time that tragic cellist Jacqueline du Pre is treated as a figure of fun.

It shouldn't work, but it does.

Psychobitches, stars Rebecca Front as a therapist whose patient roster consists solely of famous women from throughout history. Essentially an excuse for a fast-paced series of disconnected sketches, this simple premise is only semi-successfully executed by co-writer/director Jeremy Dyson from The League of Gentlemen.

Resembling a surreal parody of the great In Treatment, the series begins with a neat visual gag involving Rosa Parks - I suspect that's the first and last time I'll ever place those words in that order - before roaring into gear with Front's Grandma's House co-star Samantha Spiro delivering a pitch-perfect evisceration of Audrey Hepburn's irritatingly kooky screen persona.

Unfortunately, it then devotes far too much time to a mirthless series of Brontë sisters sketches - no, it wouldn't be hilarious if they were portrayed as gruff, foul-mouthed northerners - and Julia Davis as Sylvia Plath, which, while beautifully performed, hammers its one joke into the ground. Elsewhere, Frances Barber and a dragged-up Mark Gatiss (Dyson's League of Gentlemen cohorts crop up throughout the series) sell the hell out of a warring Bette Davis and Joan Crawford, but without banishing memories of French & Saunders' superior take on their feud. The only other sketch that really takes flight is Sharon Horgan as a glamorously self-obsessed Eva Peron.

As an excuse for a cast of talented, funny women to show off their versatility, Psychobitches is a success. But reducing Front to a straight role feels like a waste of her abilities, which merely adds to the overall air of mild disappointment.

Big Train - box set review

A sketch-show starring Simon Pegg and Julia Davis sounds like a fantasy these days - but in 1998 they were just part of this hugely talented ensemble.

This could be a first for sketch shows: episode four is the strongest yet. Kevin Eldon's ideas would make no sense anywhere else, but accumulated here they are overwhelmingly funny. Tonight, George Martin/Adolf Hitler recalls the band's late period ("Where did it all go wrong? I'm sure you've heard a lot of people say it was when the Japanese became involved"), Christopher Ryan is an Italian arguing with a tank of bolognese and, in a 1980s BBC drama, the unnecessarily good performance of the week is Julia Davis's drained Scouser.

I have now watched three episodes of It's Kevin and I'm still not sure if it's funny. Kevin Eldon's sketch show is certainly odd, with moments of brilliance, but the set-ups are invariably more inspired than the pay-offs, and Eldon's studied air of deadpan detachment walks a fine line between quirky and irritating.

But half an hour in the company of Eldon's imagination is never wasted, plus he's been shrewd enough to surround himself with an impressive array of comic performers, including Julia Davis, Liza Tarbuck and Adam Buxton.

Radio Times review

"At least it's made by somebody who cares," said up-and-coming 52-year-old sketch comedian Kevin Eldon at the start of his first solo series, just after a giant boxing glove had appeared in shot to punch him in the face. This was the joy of It's Kevin: silly set-ups other sketch shows wouldn't consider, executed with a level of care and expertise other sketch shows can't match.

Eldon has appeared in Brass Eye, I'm Alan Partridge, Fist of Fun, Harry & Paul, Nighty Night and countless other revered British comedies, its creators all knowing that his impeccable timing and oddball menace would lift their projects. Big names like Julia Davis have reciprocated by guesting in It's Kevin, but they're not just doing Eldon a favour, and this isn't just a chance for a technically gifted supporting actor to have a go at being the lead in a bunch of sketches. Eldon boldly put himself centre-screen as the host and creator of a programme that lovingly, caringly turned the sketch show inside-out. His writing is as impressive as his acting.

It began with a song-and-dance number in a bright white studio, with ticker tape, Cockney walkabouts, puppets and a thrash-punk interlude. If it had stopped there it would still have been the comedy of the year so far, but on it went, often staying in the white studio with sketches sidling in and out of Eldon's interactions with a cast of helpers. His maintenance man couldn't find the lost property office. His wardrobe assistant spoke only in screams (taken, I think, from that "goats shout like humans" YouTube video). The perfect sandwich was made by Hosni Mubarak, a curt young man with a massive dagger. A man played by David Cann explained that the best sandwich he ever had was one a found under a train seat. "I don't know what was in it. Orangey, yellow sticky stuff."

There hasn't been a sketch show with ideas this good since Big Train in 1998 - Eldon was in that as well. He reprised his famous impression of George Martin, giving the Beatles producer's voice to Hitler reminiscing about annexing the Sudetenland ("I immediately knew that we were onto something big"). But the biggest laughs were stupid visual jokes, superbly performed. The bit where Eldon failed to replace a microphone back in the stand went on for an extremely long time, but I could have watched it for longer.

The scheduling at 10.30pm on a Sunday, and the lack of on-air promotion and advance marketing, suggest BBC2 thought they had a weird dud on their hands, until scores of comedy pros shouted about It's Kevin on social media, and every broadsheet ran a profile detailing Eldon's impeccable pedigree. Then there was the odd flicker of support from the BBC online, too late: only 430,000 people tuned in according to overnight figures.

Those ratings are on a par with Stewart Lee's Comedy Vehicle - so it was that another original comedy by a rare talent pouring his heart into his career peak was seen only by the niche audience who were already on side. If people who aren't comedy nerds miss It's Kevin, they have really missed out.

Doomed romance, bad luck and sexual confusion are hallmarks of the work of both Daphne Du Maurier and Julia Davis, so this sordid marriage of the two feels entirely natural. As a homage to Rebecca and the like, Hunderby is sublime: the turns of phrase are deft, the performances both arch and loaded with menace, and the wider production impeccably detailed. Importantly, however, room is also made for a cock-n-balls gag. Davis herself is Mrs Danvers surrogate Dorothy, pining after her late mistress (whose 'broken mound was as smooth as ham') and scheming against her new one, Helene (Alexandra Roach, doe-eyed and gauche), the shipwreck survivor courted by uptight pastor Edmund (Alex McQueen). Claustrophobic and grimly hilarious in the manner of Davis's best work, this is a triumphant opener for an award-winning series. If you missed it first time round, don't make the same mistake again.
