It may be a good movie but I'm unsure if its going to be a financial break out of summer.
1-Its not for the teen set, which they are trying to attract by saying, "From Director of Dark Knight"
2-Toy Story 3, Twilight and Airbender are still going to be challenges to overcome.
3-It may be misplaced counterprogramming for the "popcorn mindless" set of summer. A better Fall release perhaps?
