Well where should I start...this farfetched 90 min underwater jaws themed movie has undoubtedly got its "jumps" but I'm afraid apart from that it has got little else to offer...you could almost predict what was going to happen all the way through, jaws 3 is probably better than this.
It's one of them movies where the victims are laughing and celebrating all the time when they think they're gonna be ok but then tragedy strikes...and they're air tanks seem to last forever.
