The movie definitely had it's ups and downs, but it was alright. The premise, though very ridiculous, is played well throughout the film. Lots of the effects were great, and the actors played their roles amazingly.
I'd recommend the movie if someone was looking for a time-waster or something funny to watch with the family, not for a family movie night. It was pretty good quality, and my family enjoyed it, but we didn't want to watch it again. It was more of a ''watch it once, now we've watched it'' sort of thing.
I don't think there could ever be a better movie about a great white shark that's killed, then reincarnated into a ghost that terrorizes a community.
