There's really a trend in going all "That movie sucks!" against every popular movie, and I'm getting tired of it. It might not be original, and maybe people can say "Oh pocahontas did it first!" but that doesn't change that it was a suspenseful, well-made film with some good points that people could think about.
I would compare it to Star Wars, really. It was an ambitious movie with a cliche plot, passable acting, and very impressive special effects. I enjoyed it in the theaters and now own it on blu-ray. It's not The Usual Suspects, by a long shot, but it is a satisfying movie in its own way.
