Id give it a 3.5 if it was possible. The story concept itself was really good followed up with great camera work and great acting but flawed by an inability to keep things grounded. Too much action was happening in such a short amount of time and characters that i had no time to get to know where dying left and right making it hard to care for anyone who died in the film. If this was a show with a bit more fleshed out dialogue and character plot along with a slower progression of the aging id say you have yourself a solid tv series on your hands. Another small complaint was the somewhat plain dialogue, which to be fair, the actors did wonderfully with what they had. The twist was cool but not well placed, there was very little doubt in my mind that people actually thought what they were doing was ok. Otherwise its a solid watch, just wished it had more that a tv series vpuld definitely accomplish
