Not amazing, and not as funny as Green Wing (but then I don't think it's fair to expect it to be). I did feel that it was a little lacking in direction, and seemed to jump between a number of characters without really establishing them properly, although I'm sure that this would be tightened up and we'd get some proper fleshing out if it came to a full series (and I suspect that it will). But I still enjoyed it; there were a few laughs through and it kept me reasonably entertained.
I think I'd give it 6/10 - not brilliant now, but showing promise.
