Suspenseful. Actionpacked. I didn't really understand the ending.

The movie kept me on the edge of my seat! I think it's a good first movie in what could be a series of movies. It's a solid film.

Great horror movie for puzzle solvers.

I enjoyed the suspense however, the ending was a bit disappointing. I was rooting for them all and to have the survivors then plan a plane ride and possibly endanger innocent people made me sad. But the concept of the movie itself was good.
