Those aren't very good scores. Anything under an A- on CinemaScore is basically a fail. It's a silly metric.
Also, Ebert's score was 4/4, he loved it.
The film is rich enough to be seen more than once. I plan to see it again, this time on IMAX, and will have more to say about it. I’m not sure I understood all the nuances and implications, but I am sure I had a powerful experience. It’s not as entertaining as “The Dark Knight,” but like the “Matrix” films, LOTR and “The Dark Knight,” it’s going to inspire fevered analysis. I don’t want to see it twice for that reason, however, but mostly just to have the experience again.
