Some people have the wrong impression about the subject matter of this film. Despite a thrilling "action" sequence within the first half hour (said "flight"), this is *not* an action movie. It's more about the toll of alcohol and drug abuse. If the R rating didn't tip you off already, be warned this is not appropriate for young children. There is excessive violence, many scenes of drug and alcohol abuse, as well as a long scene featuring full frontal female nudity.
I was impressed how suspenseful this film continued to be, even after the crush sequence within the first half hour.
Nervous flyers beware: this one will mess you up for a bit.
