ELIZABETH: THE GOLDEN YEARS is getting savagely beaten by the nation's critics. It's currently at 25% at rottentomatoes.com which is pretty surprising given the pedigree both infront and behind the camera.
MICHAEL CLAYTON is getting phenomenal reviews, sitting at roughly 90% at rottentomatoes.com; looks like another critical favorite (though probably box office underperformer) for George Clooney.
WE OWN THE NIGHT is getting mixed/positive reviews it seems; at rottentomatoes.com it's listed currently at 52%. It seems if you really like the cop/crime genre, you'll really like the film.
SLEUTH, with Jude Law and Michael Caine and directed by Kenneth Branagh, is getting pretty much killed. Rottentomatoes.com has it at 44% at the moment.
LARS AND THE REAL GIRL seems to be getting solid reviews; it's at 77% at rottentomatoes.com
