Absolutely one of the worst!!
What an extremely boring and predictable movie. A tired old theme of a haunted sub with ridiculous characters, plots and subplots. If you couldn't figure this one out at least half way through the movie, there is something wrong. You already know quickly which characters are going to get bumped off, and the "haunting" theme is so simplistic. Scare factor is a zero.
"Ghost ship" was so much better then this sad ripoff! Thank God, I didn't have to pay seeing this in a theater. Please do yourself a favor, and don't waste a couple hours of your life watching this dog.
