To paraphrase a review I saw somewhere, in ten years, when such special effects are the norm, nobody is going to look back at this movie with the affection one might have for Star Wars, or The Matrix, or other groundbreaking special effects movies that do have a good story.
On the other hand, the story is good enough, and the eye-candy is phenomenal. Blew me away in 2-D, can't imagine what the 3-D is like.
