Edge of your seat thriller. Decent acting . abetted than I expected for a low budget flick. Sharks were realistic too.

[Spoilers below]Two times the audience responded as single voice: "[The Coast Guard] will be here in about an hour" - Audience gasped, knowingly; music cue as divers rescuing the survivor reach the surface (fin) - Audience groaned, variations of "Is that 'It'?" were heard mentioned at least twice.

I would tell them to wait until they can watch it at home. The ending left you guessing. The movie was barely 1 1/2 hours if even. It sounded like everyone around us had the same opinion.

This movie had a lot of down time where nothing happened. But it has a huge twist and it was great to heat the audience reaction to everything happening in it.
