Tamsin Greig

This sitcom about a sitcom, starring Matt LeBlanc, Stephen Mangan and Tamsin Greig, has never quite lived up to its sizzling potential. However, series two does end on a high: the marriage of big cheese Merc comes under fire from all corners as he gears up for the Man Of The Year event. Plus Nigel Planer pops up as LeBlanc's lawyer - a union that promises a rich seam of comedy if he stays for series three.

Tonight's finale of this soft satire about the making of a US TV series scurries to tie up loose ends and deliver an emotional punch. As with previous episodes, it's a qualified success that doesn't quite manage to seize its comic chances. There's schmaltz: even Matt LeBlanc's character, hitherto the show's most reliably unsentimental, gives a soppy speech. Having said that, the longueurs of plot are regularly buoyed by great zingers: Episodes' strength is in causing sharp intakes of breath when characters say the unsayable. For example, slimy studio boss Merc believes his sightless wife can actually see the odd shape: "And she calls herself blind?" retorts Merc's lover. "What a b---h!" An amusing climactic scene sees fisticuffs at an awards show, and Nigel Planer delivers a wonderful cameo as LeBlanc's lawyer. At the centre of the maelstrom are Beverly and Sean (played faultlessly by Tamsin Greig and Stephen Mangan) as the Brits trying to make sense of the amoral milieu and deciding whether to reunite. Episodes hasn't hit the heights of other shows-within-a-show such as The Larry Sanders Show and Extras, but its swipes at Tinseltown score often enough to please.

Dragons! Goblins! Lizard men! Ogres! Harpies! Mermen! Succubi! Just some of the suggestions tossed desperately around a TV network brainstorming session when LA studio boss Merc casts around for ideas. It's a lovely scene that, like so much of the Hollywood material in Episodes, has just enough plausibility, not least because you can imagine that the show's writers - including David Crane of Friends - have been around the studio block enough times to have seen this sort of scattershot creativity with their own eyes.

Meanwhile, on the romantic side of the comedy, our separated writers try to cope with the fact that one of them is now dating, allowing Tamsin Greig and Stephen Mangan to squirm with awkwardness as only they know how.

The penultimate episode of this sparkling comedy about two scriptwriters navigating the moron-infested waters of Hollywood. The day doesn't get off to a good start for Matt LeBlanc (playing an exaggerated version of himself) when he wakes up in bed with his stalker Labia (Sophie Rundle). But it's nothing compared to the awkwardness felt between Sean (Stephen Mangan) and Beverly (Tamsin Greig) in the wake of Beverly's date with Rob (James Purefoy).

In a nice reversal of standard Hollywood sexism, tonight's slice of this enjoyable, postmodern sitcom, sees leading-man Matt (Matt LeBlanc) under pressure for piling on the pounds. The network bosses want writers Beverly (Tamsin Greig) and Sean (Stephen Mangan) to have a quiet word ("we need hot Matt, not fat Matt"). Matt takes it predictably poorly. Beverly meanwhile has issues of her own. She's off on her first date in a decade and needs some reassurance. Carol (Kathleen Rose Perkins) steps in. "They're going to give you alcohol. They're going to give you food. In two hours you're done. It's like a flight to Omaha."

This satire on Stateside television studio politics may be only sporadically funny, but it's buoyed up by a lovely turn from Matt LeBlanc, who sends up his big-shot persona in style. In tonight's episode, LeBlanc struggles to persuade his former Friends colleagues to cameo on his faltering new show Pucks! ("Look Courteney, I understand - if you can't do it, you can't do it... but can you give me Jen's number?"). Meanwhile, Morning (Mircea Monroe) tries to set up Beverly (Tamsin Greig) with her raffish younger brother (James Purefoy).

When it's on song Episodes touches the parts other sitcoms don't reach. The comedy of Californian manners can be taboo-trashingly funny, as it is tonight when a chain of farcical cause-and-effect plays havoc with the adulterous adventures of Merc and Matt. There are a couple of yawningly tasteless subplots for good measure, one involving Matt's young stalker (whose name is Labia) and the other involving a cosmetic-surgery malfunction for his blonde co-star. Yes, the scenes where Carol moans to Beverly (Tamsin Greig) about her directionless affair have become a bit of a drag, but you can't have everything.

Pucks! takes a time out tonight when news breaks that Merc's father has died, furnishing the writers of Episodes with all the tragicomic potential of a funeral. As with so much of this series, it's a qualified success, as a procession of competitive mourning techniques (muffin basket? charity donation?) open up further faultlines in Sean and Bev's moribund relationship. Stephen Mangan, Tamsin Greig and Matt LeBlanc are now displaying the sort of relaxed chemistry that only comes with time, and the latter struts off with most of the best lines (the less politically correct, the better). But the attempts at pathos fall flat - these characters haven't done enough to earn our sympathy yet. And why sideline Daisy Haggard, whose formidable arsenal of disgusted expressions was such a pleasure in Series 1?

The satire isn't always subtle, but there's still much to enjoy in this British-led LA-based sitcom. It's the Americans who provide most of the laughs. Tonight, network head Merc Lapidus's (John Pankow) father dies, prompting a flurry of competitive condolence gifts ("a turkey the size of a Prius") that leave Brits Beverly (Tamsin Greig) and Sean (Stephen Mangan) utterly bewildered. Matt (Matt LeBlanc), meanwhile, is nervous about attending the funeral. He's having an affair with Merc's blind wife ("it's good, you don't have to suck in your gut").
