I used to use a mix of Yahoo movies and IMDB, then Yahoo movies dropped most of the information I used it for and replaced it with eye candy. I no longer use Yahoo movies, now IMDB is the first place I go to for new info about a show of movie, then I usually find a good wiki for the show or movie depending on the detail I'm looking for. A Networks show info and movie websites are usually not very good.
Way to go IMDB!
