Very realistic depiction of something that 'could' happen. It is more likely to be an Asteroid than a comet, but the results would be the same.

Amazing movie, a fresh take on end of life type movies. Acting was great and movie was action packed beginning to end. A must see for anyone who loves these types of movies.

It was awesome.. when it comes out on dvd i would buy it...

The movie was excellent. However, the constant rebuffering was annoying. It took 3 hours to watch a 2 hour movie. Not sure why there were so many times the movie stopped. One time it stopped for a half an hour before I restarted the movie and it started where it had stopped. But the movie was very good and I would highly recommend to my friends.
