For great coverage of 'serious' cinema, check out Strictly Film School. It's by far the best individual site on contemporary film that I've come across.

Meanwhile, for all the ratings and reviews of more mainstream fair, check out Rotten Tomatoes.

Finally, if you've been haunted all night by which movie Brad Pitt first appeared in (No Man's Land) or who directed Metropolis (Fritz Lang), go to IMDB.
