This was one of the best movies I've ever seen. I thought that they should have made more out of the ghost idea, though. They also should have added on to the dreams and I thought that they shouldn't have killed the people so close together. This movie could have been a lot longer and they could have had more fun with it, seeing they were on a big boat, there could have been a lot of surprises, but for what was on this movie it was good enough to watch again.
