WLIIA is at its best perhaps the epitome of improv humour. Performers come up with gags on the spur of the moment that I, for one, still have rattling around my skull as Memetic Mutation
years later. Not every episode will be equally funny, but the overall standard is excellent.
So let's go to the elephant in the room: the UK vs US versions. Firstly I think people ignore the fact that the UK version was very different at its beginning and end: its later series were more similar to the US version than to its own early series (which were a bit too slow-paced and highbrow). The late UK series are my personal favourite, including the one transitional series that was filmed in Hollywood but with Clive Anderson as host. Those episodes have Colin, Ryan, Greg and other great performers, but also an audience that doesn't treat anything happening to anyone as "And I Must Scream
" and Clive Anderson, who is IMO a superior host. Drew Carey isn't a bad host but he can't keep up with the performers and so we just feel bad for him when they mock him, whereas Anderson could give as good as he got and thus we enjoyed it when he got taken down a peg or two.
Really, though, the show is always at the very least watchable, and often laugh-out-loud hilarious, regardless of the version.
