For all the hype it got I was expecting a lot more!

In truth, there is barely enough story here to make a film.

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."

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.
