I haven't seen the new Superman movie, but I picked up a used copy of Batman Begins and watched it a couple of nights ago. What a surprise. Nary a primary color in the movie. Very dark, like th re-invention of Batman a few years ago as the Dark Knight.
I really respect Ebert as a film critic, but you can throw his comments out the window when he reviews anything related to his childhood or comic book heroes. He becomes a little Gee Whiz kid again (which ain't all bad) and filters everything through his own childhood.
