The big list of sitcoms on the site is now fantastic. There isn't a British sitcom I can think of that isn't there. With this list, I'm going to attempt to name my top 100 sitcoms. Anybody else fancy doing the same (do top 50 if you want). You're going to have to make snap/controversial decisions. Show us what you're made of and come up with a list.
I'm game. I might have to start with 50 though rather than 100. After say, my top 20 I might be hard pushed to put them in any order. But I'll give it a go.
Def.
Good Man
