Saxondale

Steve Cougan has and is struggling to get away from his huge success with the comedy icon Alan Partridge (which I re-watched recently, it's outstanding).

But I think that with Saxondale, he may succeed. It succeeds in breaking from Partridge, it's very funny, and it's... I think it's original. You need to adjust when you start watching it, it's not your father's sitcom, as it were. Just the first three minutes made me sit up and look forward to the rest.
I like Tom Saxondale. He is not such a prat as Alan Partridge. He may be a bit of a blowhard, but he has brains and a good heart. And as a character, he has an interesting and well played struggle with his temper, which gives him depth while also being played humorously.

... Isn't it funny, by the way, almost any actor would give a kidney to have a success on the scale of Alan Partridge, but when they do get it, they spend the following years trying to get away from it.

Another equally funny and seminal new britcom is Gavin And Stacey.
