The effects in this movie were great! Visually they did a fantastic job. The plot was an interesting amalgamation of elements pulled from several of the books, plus some creative license with some of the major events in the original story. Overall, I enjoyed it, but I wonder if I would have felt differently if I weren't comparing to the books? There were a few slow moments, but lots of action. Unfortunately, the actor they chose to portray John Carter did not have the "larger than life" hero quality of the character in the book. He seemed very... mortal.
