Not even a cameo by Tamsin Greig can redeem this painful adaptation of Euripides' The Trojan Women. For an hour and a half it screams with anguish, verging at times on the parodic. The production is a puzzle. Caroline Bird has updated the language, stripping the original of much of its poetry and adding expletives.

Affairs, arguments, accidents. Feminism, marital failure and a fear of ageing. Jumpy has plenty of conflicts and issues, dunked in a wonderful bittersweet humour. But while April de Angelis faces uncomfortable truths, she fails to deal with them with equal courage. This play gnashes its teeth – at the gap in communication between generations and at the eternal pursuit of youth – but it lacks bite.

There are a few things wrong with Episodes, the comedy series in which Stephen Mangan and Tamsin Greig play a British scriptwriting couple who take their hit sitcom across the pond, but there’s a lot more that’s right with it.

There have been some highly unlikely couplings in the long history of television comedy, but the one between Debbie from The Archers and Joey from Friends in the first series of Episodes ranked somewhere near the top of the list. If the viewers struggled to be convinced by that oddly implausible tryst, at least we weren’t alone. It turns out Tamsin Greig’s character Beverly Lincoln can’t quite believe it happened either.

“Why does anyone ever have kids?” By the time a character in April De Angelis’s new comedy utters this exasperated exclamation, there are many in the audience - whether parents or children, or both - who must have had the same thought. And more than once in the evening. For this exceptionally hilarious and perceptive play, which opened last night, not only tickles the insides of your arm, but also lights up the senses and then gives you a quick cuddle, too.

Episodes may prove to be the zenith of television’s obsession with making television about making television. It was certainly a handy primer for anyone who fell asleep around 2000 (perhaps during My Hero; you are forgiven) and missed all the dominant strands of TV comedy emerging over the next decade. We hadn't simply been here before; Episodes was incubated in the post-ironic, multilayered comedic landscape in which we all now live. The success of the US version of The Office was referenced within the first five minutes.

The accepted wisdom that Americans screw up every British comedy they buy the rights to is to be given a post-modern twist. Shooting was announced this week for a new sitcom called Episodes. It features a pair of British comedy writers – they also happen to be a married couple - whose idea for a new sitcom is purchased by a US broadcaster. The twist? That they must replace their lead actor, a distinguished RSC veteran played by Richard Griffiths, with the notably one-dimensional Matt LeBlanc.

Tamsin Greig takes her mighty stage chops to a new level in The Little Dog Laughed, a minor Broadway comedy that gets a major star performance from Greig in her first West End role since God of Carnage. Tearing into a role that deservedly won its New York originator, Julie White, a 2007 Tony Award, Greig gives a cyclonic performance in a play that suffers palpable subsidence every time she leaves the stage.
