If I am really looking for
serious film criticism, I always look first for Stanley Kauffmann's reviews (New Republic). He is not as accessible as most critics, and definitely does not write for a general audience, but for serious students of film, there is no one better....
For general takes, I usually go to IMDB's "external reviews", and often check out Roger Ebert, David Edelstein (Slate), Stephanie Zacharek (Salon), and a random sampling from the lists...
I also like a local alt.press critic, just because I regularly read him, and have a sense of his tastes (and can "read between the lines" to sense my own response): Devin O'Leary (
The Weekly Alibi, Albuquerque).
