Like Pirates of the Caribbean, but imo much better. No dorky self conscious British accents, more real creativity. Surprisingly good dialogue and storyline. You'd think the action would be noisier and the characters flatter since this was based on a video game, but the story lasts well. It's the kinda fun movie you wanna watch again-- because, somewhere in all the romantic action adventure fantasy, there is something real. You are somewhere in it.
Personally, I think Ben Kingsley rocks the villain role and the Hassansins are freaky scary and highly effective!
