Flixster.com combines the data on IMdB.com with all network-y goodness of FilmTrust and the user-submitted content of MySpace. The interface isn’t quite as horrible, and there’s lots more to do there than surf your friends pages. Witness: I just spent much of the last few hours there and I have no friends in the system. (Although I do have almost 30 Facebook friends using it through their integrated application.)
The main benefit for me over IMdB (which I love) is the ease of surfing movies and the simplicity of rating and reviewing. The associated drawback is that there is much less rich information about each film, performer, and crew member.
But wait, there’s also widgets!
