I was just blown away by it the first time, and I finally just went out and bought the DVD...it was a gift to my parents for their anniversary, because they seemed to really enjoy the movie, but I think I've gotten more use out of it.
Johnny's great as almost anyone/anything, but yes, he's spectacular as a pirate. Did you know they're supposed to make, I believe, two sequels? I can't wait to see them.
