This is a tender, generous movie that likes its characters and presents them as real people, full of flaws and strengths.

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.
