The premise of the movie is interesting. I mean, who doesn't like a murder mystery, especially the idea of it being at sea, characters disappearing one by one and the audience wondering who it will be? It was enough to make me want to go rent this movie.
However, the problems with this movie come from a plethora of areas. First of all, the acting is pretty atrocious. The characters seem a little wooden, seemingly just going through the motions of the script, and, because of this, many of the scenes kind of just die (no pun intended). Another perplexing element is the preposterousness of having a killer aboard a tiny boat, and no one seemingly being able to see or figure out who it is. Are we to believe that no one can hear the victim's screams as they are being attacked? Perhaps the most annoying aspect of the film is the over abundance of plot twists (as one reviewer mentioned), and the attempt to explain them all away in the film's final twenty to thirty minutes. This really is a disservice to anyone who actually tried to follow the film. The dark and murky camera scenes make it hard to figure out what is going on much of the movie. Finally, what's with the odd choice of background music during the film? This completely kills any sense of suspense this movie is supposed to have.
This is an average movie at best. At worst, it isn't very good.
