The production values would indicate someone spent some bucks on this film and cast. It's too bad they didn't pre-screen it with someone other than a ninth-grade gamer to check for plot holes big enough to drive a Hummer (and then elevator cab) through.
My biggest problem is with the look and feel, and that falls on the director. Scenes that didn't have to be shot hand-held were, even when a simple tripod would do, and the effect is nauseating; don't show this on a boat, anyone prone to sea sickness will be sent right over the edge by the constant shifting of the frame.
Also to the look and feel: Why does every Sci-Fi/SyFy movie have to look like an X-box 360 game? What happened to the good old days when directors knew how to set up a shot and a scene? If you have to push this hard to engender some sort of excitement, then the plot needs serious assistance.
Don't make the mistake I made. I kept watching and hoping something original or interesting would happen, but this is nothing more than a static version of Half Life, Black Ops, or /insert your favorite video game here\.
