Blair Witch meet Jaws… was the pitch. This is a real mixed bag. While I can’t deny how chilling it gets at times, most notably in the end credits, it’s still almost hilarious… if it’s meant to be scary, that is.. This could have been a near perfect comedy, “Look, Sharks! There’s Two Stupid People in the Water! Get’ Em! Get ‘Em!” And the fact that the only true story this could possibly be based on is, “well, these two people went missing, and well, they went missing…” makes the whole thing even more unintentionally funny. Worst is when the young couple start saying stuff like, “oww! something bit me or stung me or I don’t know!” and CUT TO: a jellyfish; and then later, “oww! something bit me or stung me or I don’t know!” and CUT TO: what looks like a piranha. The acting is truly awful, and it’s not like they even needed unknowns here…. I couldn’t help but thing during this movie that it’s the kind of movie a pair like Jennifer Aniston and Brad Pitt or somebody could have made, playing a variation on themselves – I mean, I’m sure it’s not unusual for actors to go out on these scuba-diving missions; true story basis be damned. I wouldn’t normally really want to see actors like this in much at all, but here, the filmmaking was actually so good, and the acting so bad, I couldn’t help but think it could’ve been so much better.
