It was good. Very much a B-movie in some ways (Of course the plane is eventually landed by a guy whose only experience is flight simulators! Of course the couple joining the Mile High Club get bit first!), but Samuel L. Jackson was the proper badass, the other characters were fun and interesting, and... you weren't sure who was going to die in the snake attacks. That made it a compelling movie.
And yes. I was hungry afterwards.
