wodmarach: UK or bad US version?
TheEnigmaticT: Ryan and Colin are awesome in either version. Yes, Drew Carey has all of the personality of a dead fish, but Wayne Brady is brilliant at improvisational singing. Also, I can hardly understand the guys in the British version half the time, so my vote has to go US.
If you like Colin, he's absolutely brilliant in that short lived Canadian series "Almost Heroes." He steals damn near every single scene he's in. It's a shame that it only lasted for 8 episodes and most people have probably never heard of it.
Who's Line is it anyway got progressively worse the more American it became. It was great when it was just UK personalities on the show and it was great being in the UK with American comedians, but the fully American version just wasn't anywhere near as good.
