Loved it from start to finish. Forget all concepts of normality, take it for the story that it is. Too many people expect to much reality from movies, but sometimes it is just that, a story to enjoy, so sit back and enjoy. Chris Hemsworth plays a his role well. Compassionate and caring, and then as the plot thickens, his character flawlessly changes. Miles Teller, plays his role with Compassion and you find you do actually care about him and Jurnee Smollett, who you find yourself fully sympathising with. Both are stunning. Mark Paguio plays his role well. It's clear from the outset that he does not agree with the experiments. Overall... very watch and enjoyable.
