I highly value and respect your comment about watching something until the end. The programme is NOT over until the credits have rolled. Bless you for being so considerate. My wife and I got really annoyed with some people at a cinema when they decided to want to walk past us while the credits were still rolling. As you so rightly pointed out, had it not been for those people, there wouldn't have been a movie in the first place. So show some respect.
Well, if I think of any other UK shows that might be worth a peek, I'll let you know.
Oh, not that I have seen it myself but I hear 'The Office' is supposed to be quite good but as I said that's purely hearsay.
There is also the Johnny Vegas movie
Sex lives of the Potato Men and the series
Ideal which you might like. Check them out on IMDB.
