Pretty good movie overall. First half was nothing special but it got better as it went along.

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 film's masterful storytelling did its job. The message was clear. No need to overdo.

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
