I typically don't leave movie reviews unless the movie is REALLY GREAT or REALLY TERRIBLE.... This movie was in fact REALLY TERRIBLE... I kept waiting for the movie to get better; but it never did.... The acting was mediocre at best. The movie was completely unrealistic in regards to safety procedures and protocol. I don't want to tell the movie but everything about it was terrible... The ending was absolutely AWFUL; as there was no conclusion on what was going to happen. There was no reason to go get more air if in fact only two people could POSSIBLY survive.... Awful movie. Please do not waste two hours of your time like I did.
