Morgana Robinson is the new comedy wunderkind who has gone straight from bit parts in cult shows to her own five part-series. But there's a huge gulf between being funny for 90 seconds in one sketch and holding together a whole 30 minutes. The opening sketch of Bozza as a schoolboy with Tourette syndrome was quite funny - if rather familiar - for about 20 seconds. Dragging it out for a couple of minutes killed it entirely. The rest of the show followed much the same pattern. At her best, Robinson is one of the sharpest and funniest comics around: unfortunately, this show didn't do her any favours.

We must part with our celebration of female- fronted comedy, thanks to The Morgana Show, a witless sketch vehicle for newcomer Morgana Robinson. Why has she got her own show? Is it because her agent is the powerful John Noel, who numbers Russell Brand among his clients? I wonder.

Like the similarly charmless Katy Brand, Robinson's toothless parodies of the likes of Boris Johnson and Cheryl Cole are an apolitical affirmation of the celebrity status quo, not an attack on it. They lack the backbone required for anything other than staggeringly uninspired whimsy.

And when Dom Joly escapes from the jungle, someone should alert him to The Morgana Show's suspiciously familiar bellowing mobile phone businessman. Shameless stuff.

The Morgana Show, Channel 4, review

Ceri Radford reviews the new sketch-based comedy show starring new talent Morgana Robinson, whose impersonations include Cheryl Cole and Fearne Cotton.

The Morgana Show couldn't be more different from Frankie Boyle's show [which was scheduled before it]. Slow-burning, character-based sketches which often didn't go anywhere but were mostly watchable purely because of the performances. Morgana Robinson came to the attention of Channel Four executives after sending in a home-made DVD and was fast-tracked to the cast of the TNT Show before being given her own series.

Many of the sketches featured brilliantly crafted characters, such as has-been Hollywood actress Madolynn, but lacked any funny lines. There's no doubt that Robinson is an excellent character comedienne, and does the best impression of her good friend Fearne Cotton that you are ever going to see, but too many of the sketches felt like nothing more than a showcase for her acting abilities without providing much humour. There were some exceptions, such as a really enjoyable sketch about a couple who run a funeral home.

While it wasn't brilliant, there was enough quality in The Morgana Show to deserve a look at the second episode, which will feature some more characters. Which is probably more than Frankie Boyle's Tramadol Nights deserves, sadly.

Morgana Robinsons deranged creations in The Morgana Show should delight anyone with a thirst for League Of Gentlemen-style weirdness.

Whether or not she makes you laugh, Morgana Robinson is without question a staggeringly brilliant vocal and facial mimic. Her Fearne Cotton and X Factor bits aren't her finest, but it's spooky how she manages to morph into her targets. Morgana doesn't just look like Fearne Cotton - she is Fearne Cotton. She's also extremely funny. Morgana's from-scratch characters are cleverly conceived, weird but recognisable enough to not feel like you're being pummelled by surreal in-jokes. Best are the crazy old lady who thinks little people live in her radio, Madolynn, a spent drunk and one-time Hollywood siren and Gilbert, the socially incompetent teenager. Well done to Channel 4 for not wimping out and stashing Morgana on E4.

The Morgana Show: why we need more female comedians

Channel 4's new Morgana Robinson-fronted sketch show is funny and cutting - qualities many male-led comedies struggle to achieve.

Characters in Morgana Robinson's new sketch show include a washed-up Hollywood actress, some local news reporters who go overboard with the light-hearted banter ('We like each other!' they boom) and some grunting hicks. It's loud, bold and physical - the sort of show that will probably beat you into submission.

I know what you're thinking: Morgana who? The funny girl isn't a household name, but we expect that to change after Morgana Robinson's debut tonight.

The 28-year-old's impressions made such a big, er, impression on Channel 4 talent spotters that she got her own five-part series without having to do the usual Comedy Showcase pilot first.

Her Fearne Cotton sketch is so spot on you'd be forgiven for thinking the Radio 1 DJ was doing a cameo, and being gorgeous as well as fluent in Geordie makes Cheryl Cole an obvious target.

She does a mean Dannii Minogue too but many of her comic creations - like a faded Hollywood siren - are characters she's created from scratch. And she's just as funny when she's dressed up as a fella. You might have already seen her awkward pre-teen Gilbert on C4's TNT Show and she also does Boris Johnson as a schoolboy. This may be the first you've heard of Morgana - it won't be the last.

Little-known comedian Morgana Robinson brings her own sketch comedy series to Channel 4. It's pretty standard stuff for late-night comedy - a bit surreal, occasionally amusing. She sends up celebrities such as Fearne Cotton and Cheryl Cole as well as performing her own original characters.
