Pro's: It ends.
Con's: It's boring, boring to the point of complete tedium.
The characters are the most, miserable, nasty and downright unlikable cast you will ever see. I literally wanted them ALL to die.
The effects, they're aren't any, a little bit of blood in the water and lump of rubber that jabs into a leg over and over as the camera shakes around all over the place, so you can't tell what you are looking at. You NEVER see the monster barring a quick flash of some kind of teeth in the last few minutes.
The plot, seriously, it actually does have a nice idea in there somewhere but the story just keeps jumping from one set of people in one location, to another set in another location, while trying to cleverly follow about 5 different story threads. It just becomes confusing and fails miserably. The actual monster plot takes up about 5 minutes of the whole film, the rest might just as well have been a dull family drama.
The camera work, sound and lighting in this film are dreadful. Shaky camera work, bad lighting and sound that at some points, is so low that you can't hear anything and then in other parts, it's loud and bellowing.
The artwork for the poster is misleading and the people named on the poster are only in it for a few minutes. James Duvall must have about 2 or 3 minutes of screen time, it's ridiculous.
All in all a really dull, boring and poorly made, horror (sniggers) film. Avoid!
