The movie plot was predictable and adolescent with the dialogue on a 5th grade level. The Lord of the Rings trriology , by comparison, was far superior in that regard. But the 3-D -/IMAX experience was well worth the cost of the ticket.
I doubt I'd want to see it again or even purchase it on DVD. If you plan to see it be sure to get there early so you are not stuck in seats too near the screen.
