Intriguing concept (which understandably attracts a stellar cast) only to create a film with such diminishing derivative and contrived returns... This is an issue where the writer, producer and director are largely responsible. About as good as 'The Maze Runner'.
I'm not sure if I prefer the gaping plot holes or the scene where they all get drunk, have a foam party and make out because having near-death experiences made them hornier (?) or this Wikipedia line: "Sophia is haunted by a girl named Irina whose life she ruined out of jealousy by hacking her phone and sending out her nudes to make sure she was valedictorian. They realise there is a downside to flatlining."
