I also agree with Ben that it is just a fun movie and not meant to be Citizen Kane II. I remember similar bad reviews of The Matrix. The makers of The Matrix were lovers of kung fu movies and action hero sci-fi comic books. They wanted to bring the feel of those comic books to the big screen using real actors instead of the usual animation. Some reviewers who trashed the film were looking for some "deeper meaning".
Back then I got a chuckle reading a couple bad reviews of The Matrix, where the reviewer actually said it felt like a comic book thinking their comment was not a compliment; when of course it meant the filmakers succeeded.
