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."

The best films of this genre always show a path and provide a takeaway for being a better person.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

The movie turns out to be a little better than the average. Starting from a romantic formula often seen in the cinema, it ends in the most predictable (and somewhat bland) way.
