Everyone I know seems to just call it "the pirate movie," which is fine by me. Saw it last night with Elizabeth. Arrrr! This movie buckles a large amount of swash, and buckles it good and proper. Undead skeleton monkeys rule.
If you wait all the way through the credits, incidentally, there's a fifteen-second stinger that's kind of cool. Movies these days seem to be starting to include extra scenes designed to be watched only by ushers.
