Blackadder is fantastic, Rowan Atkinson's funniest role IMO, far better than Mr Bean amongst others.
I especially love the second and third series, where Blackadder's sarcasm is at it's best. Can't beat the fact that you've got Hugh Laurie and Stephen Fry in it as well.
Fourth season, whilst funny, I found a little harder to laugh at, what with it being set in the trenches and all. Still excellent, and I have to admit finding the final scene when they storm over the top very touching.
