Well made. Some good moments of tension. The story is nothing special but the setting makes it interesting. Not much replay value once you've watched it. Very illogical at times but I managed to ignore it before it ruined the movie. The very end is completely ridiculous though.
Worth a watch. Thriller with more action than twists.
I normally rank 'em as "meh," but I'm "fair" thanks to watching Keith's current? wife swim twice & my affliction w/ aquaphilia.
