DBF, my sister, and I saw it last night and we all LOVED it. I thought it was just as good as the first one and the special effects were fantastic.
I also loved the way the story moved, although it seems many of you didn't. We already knew the characters after the first movie, there's no need to rehash their personalities. I found the exploration of their minds much more interesting...how Jack became the way he is, Elizabeth performing an act of "piracy" while Will tries to be good, etc. The end was really a twist as well, seeing Barbossa again and the crew's declaration of where they're all heading. I can't wait for number 3 next year!
I've seen alot of critics predicting that Dead Man's Chest is going to shatter the one day opening and weekend box office records that Spiderman 2 currently holds. We shall see.
