"I'm humbled and I'm proud," says Andrew of being included in his former foster father's will, to a disgruntled Stephen, who scoffs at the logical inconsistency. Business as usual in one way, then, for the Robert Webb/David Mitchell team in episode two of Simon Blackwell's dramedy, which involves a sly pop at the practice of baptism and sees Andrew stage a festival to help keep the pub afloat, while ramping up the sibling rivalry several notches.

TV preview: Back, Episode 2, C4

When writer Simon Blackwell's new series starring David Mitchell and Robert Webb was launched last month publications were sent an episode-by-episode breakdown. But shortly afterwards we were asked not to publish it as it was felt it would give too much away in advance. Having now seen the second episode I think I can see why.

Back, which began on C4, can be read in a few ways. Back as in, David Mitchell and Robert Webb are back, together, hurrah: the Peep Show guys reunited, and playing quasi simulacra (the sober, moral but sarky one, and the smiley shallow one). Back - as in Stephen's dad, a pub landlord and inveterate foster father, has died, and the mourners suddenly include Andrew (Webb), who was fostered for about 10 minutes back in the lost 80s, and they will replay their memories of those days with wildly differing degrees of enthusiasm and accuracy. Back - as in, you can never really go there.

It's a triumph, in that writer Simon Blackwell looks to be embarking on a grown-up exploration of memory that manages to be in parts explosively funny, too. Mitchell's character (as ever) reveals himself as too clever to pull off real pathos: Webb's (as ever) as too misguided to garner real dislike. Painfully sharp but also oddly touching, if you let it.

Back review

Back doesn't have the most straightforward of premises; it takes a bit of setting up. But that's done well, and it's worth the effort, because once you're on top of things, it's an interesting place to be.

Back, review: the chemistry's still there

Back is far less claustrophobic and far more of an ensemble piece than Peep Show, though some of the acting in the first episode felt a bit too broad.

Back, episode one - Mitchell and Webb triumph

"Mum's gone for a wicker coffin. Reminds me of the baskets we used to serve pub food in. Dad's like a giant scampi." Pitch-black comedy Back (Channel 4) began with a death in the family and immediately found the funny side.

Back: One of the best new shows of the autumn

What's Andrew up to? Is he just a chancer or is he much worse than that? Waiting to find out adds an intriguing, almost psychological-thriller element to what already looks like being one of the best new shows of the autumn.

Back is a promising imposter comedy

David Mitchell could just stand there and pull a face - you know, that face - and I'd be happy.

Back is not Peep Show: The Next Generation. But it also sort of is, inescapably.

Mitchell & Webb are 'Back' in Channel 4's new sitcom

So I'm happy to report that Back bucks Blackadder. This is a confident, charismatic opener of what promises to be a great little series. Here's to British comedy in rude health.
