I thought it was a decent movie. Saw it in theaters when it came out.
Liam Neeson is a great actor, but the movie plot was not very well put together. [Spoiler] In the beginning when he tries to commit suicide its just pretty sad for a good hunter to come to that, but he had his reasons.
The plane crash was realistic IMO. it would be hard to salvage anything including weapons and everything would be broken and all over the place. Hard to believe they didn't even have pistols though.
I guess this movie was really the worst case scenario for the particular setting. Its believable enough for me. I'd probably be dead or die just as bad in that situation of extreme weather and elements.
Someone mentioned not having celphones. In that remote location and extreme weather celphones wont work anyway. that is a moot point
