First of all this is not an hour and 30 minutes of a high action survival film. Rather a morally grey character drama focusing on people's interpretations and motivations before and after the "trip." And in that sense if you go in with the right expectations you will be happily pleased. Every scenes is well shot, and superbly acted and lots of characters are well known. This story delves into people's moral compass. And sometimes the truth isn't as black and white. You can't say too much without spoiling it but it leaves you thinking, and certainly uneasy. It's not a cut and dry film in terms of good or bad and that there is where the film succeeds. Theres lots of lessons to be taught from this film as well. Would highly recommend for those looking for films with deeper meaning and asking tough questions about our morals and motivations.
