I agree with @watson387 that Omar Epps was outstanding, and indeed was a big part of what made this worth watching. But, I also want to give kudos to Kate Walsh for going outside of her usual comfort zone, and tackling a role that is unconventional for her. The chemistry between her character Jackie, and Epps's John Lane, does indeed work well, even when they're ticked off at each other, and, even more so, when, circumstances, (and some badly behaved guests) cause them to be separated. Then, realizing possibly too late that what he had may be lost forever, he has to MacGyver together a plan to rescue her, and save them both, all the while hanging on to his own sanity by a thread. Everyone likes to believe that they would act nobly, bravely, and would do the "right" thing in trying circumstances. But as recent events have shown us, the meaning of nobility, bravery, and the "right" thing to do, can mean VASTLY different things to different people, now being defined along tribal lines, rather than moral ones, unless of course, one defines their morality along the same lines as their truth, that is their feelings vs. actual facts. That being the case, it is easy to rationalize ones actions, no matter how violent or destructive, notwithstanding any harm it may cause to others, it becomes Lord of the Flies meets Darwinism, every man for his tribe or himself. Thus we see each of the characters here come to grips with the thought of being the sole survivor, and either dealing with it head on, or, curling up in the fetal position of self pity and futility. It makes for an interesting case study, and, I was glad I stuck around to the end.

BORING RUBBISH THAT OVER STAYED IT'S WELCOME. I EXPECTED BETTER WITH THE LEVEL AND CLASS OF ACTORS. IT JUST WASN'T THAT INTERESTING AT ALL AND THE DIRECTING WAS JUST SHOCKING AND JUST ADDED TO THE DREARY BORDEM SAME AS THE WRITING DID. NO RATING.....

Should have been better with the quality of actors. Directing is awful and movie logic is questionable.

I am really disappointed about this film. The plot is very predictable and it follows a generic template for creating a Sci-Fi film with an initial group of people that dies one by one. It's pretty predictable what happens to whom. I would rater that they focused more on "The Event" than it being almost only a footnote.
