Why so much hype?

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."

A movie that not only functions as a solid scarefest but a razor-sharp satire.

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