It used to be a very nice, excellent site, but then somebody decided to change everything, and now it is terrible, total mess...

AMG's All Movie Guide is my preferred internet source for movie information. Though not as detailed and inclusive as IMDB, the site has a better/cleaner layout (in my opinion) and includes professional summaries and reviews. Some downsides (resulting in a loss of a star) are that there are no public reviews, no headshots of the actors, and the search options of more limited.

Full of good info on films and genre. I'd give it a 5 if it weren't for its limited search options (only movie titles/individual names allowed).
