Can I please get one thing straight - if a film has a jumpy moment near the beginning of a film, it HAS TO KEEP TO THAT JUMPY THEME! You get one jumpy scene with a clock, then that's it folks - Ghost Ship is flawed from the start. A scene where a boat full of people are killed by a metal wire that rips them all in half? I'm sorry, but no. Just no. It didn't work and I still don't get why it had to happen or why the villain had to exist in the first place, let alone the movie.
I was told by two horror fans it was, and I quote "...alright". WRONG! It was one of the worst films I have ever seen. It seems to be suffering from what shall henceforth be known as the Paranormal Activity effect: the PA effect is where a film tries to make itself out as a good film, before failing after about 10-20 minutes (in most cases). In this film it took about 20 minutes for me to get bored and start half watching for a while until the ending.
The only major attractions of the film are the ending (after the bit that belonged in a PG or a U (to be honest, that bit was ripped off from Pokemon The First Movie!)) where you find out something that gives the film a perk towards a good horror, the brief scene of nudity and the violence. If you are the sad sort of person who only wants a little bit of violence, poorly chosen music for the setting, and A pair of breasts, then watch this.
But for those people who have taste and want to watch a good horror film, let this movie sink like the Titanic!
