Every time I watch this show, I find my self laughing all the time, and feeling bad for one or several of the characters half of the time. There's so many embarasing sex related humourous scenes. The cast and the characters are amazing.
I think there were made a similar sitcom in USA, but in my opinion it was not even half as good as the British one. I'm no fan of "The Office", but I think that show also was a whole lot better Brittish style. In other words: This series might not get the highest ratings in the US, but to me (European) it's one of the best comedy shows out there.
