I've just read this thread in it's entirety and have really enjoyed it
I live in the UK, but I haven't watched all the shows mentioned, just because I don't have much time for TV these days. That said, if my Facebook NewsFeed is anything to go by, it looks like you're in with the majority of the UK when it comes to most of these shows lol
Of the shows mentioned in this thread that I did watch, I've loved them all (especially IT Crowd, Green Wing, Books, Misfits, Shameless and Peep Show).
Anyway, I don't think I saw Inbetweeners mentioned. Easily one of the best shows to come out of the UK in recent years. It's finished now, but they ended it with a movie (also well worth a watch). I've seen a few episodes of the US version and, tbqh, they were awful. Completely murdered it. Watch the UK version, I insist
Also, I don't think anyone has mentioned Mount Pleasant. It's not AMAZING, but it's watchable. It's easy viewing. Somewhere between a drama and a comedy. You might like it
If anyone has mentioned either of those, oops, my bad. I can't remember every show that's been recommended :/
