The characters are intentionally one-dimensional which works SOMETIMES. Bill Pullman is the most believable as Jack Wells, him and Bridget Fonda have good chemistry. I don't like it's misogyny, though it is meant to be farcical and not to be taken seriously by the astute viewer; I think the display sends the wrong message. This film is never tedious.
Quite bland and well equipped with a by the numbers plot and archetypes, but that could be it's strength as a modern day B-monster movie. I read that this is supposed to be a horror comedy; however, it failed at the comedy part, but because of my love for Jaws I have a weakness for underwater tension stuff. Gets another star for the Betty White twist and how they handled the Pullman/Fonda relationship.
