Written by guest reviewer: Bruno, our dog.
It was only fair that this film should be reviewed by someone with the kind of intelligence it was obviously aimed at, so therefore I've been given the job.
The humans I live with have watched some bad monster movies, but this just about takes the bonio. It opens with a few facts about Megalodons and when they existed. This little lecture tries to be educational but is completely muffed by the very title of the movie. Then the action kicks off with a tedious over-length prologue. A couple of irritating girls are eaten by some unseen water monster, intercut with scenes of characters in white coats shouting at each other. Before long a group of women in bikini tops are stranded in a remote location where men in black vests are holding them at gunpoint demanding they dive into a shark-infested lake to rescue a stolen painting.
If this is the way humans carry on I'm glad I'm a dog.
The best thing about this film is the hilariously bad CGI shark (think school computer package). I've seen scarier cats. And the epilogue is mildly funny, at least displays a sense of comic self-mockery. Unfortunately most of the film is a paw-curlingly bad mess of terrible dialogue, tedious 'suspense' and actors who are constantly out-acted by the trees in the background (which I thought looked very inviting, by the by).
If you want a film about a prehistoric shark then see the far superior "Dinoshark". If you want a film about stranded people trapped by some dangerous animal then see "Rogue". Or better still, save the money and buy some choccy treats for me.
