I finally saw "Dead Man's Chest" this weekend. There was a woman in the row in front of me who was easily scared. The Krakken scared the crap out of her. On the whole, good movie.
P.S. I just remembered something funny from when I saw the first movie. There were a lot of trailers. When a trailer for "Master and Commander" started there was an image of a boat. Everybody in the theatre thought that the movie was starting so we all started clapping, and 30 seconds later, everybody felt really stupid.
