It's entirely possible that sending the audience out feeling lousy was intentional

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."

Although I seem to have had higher expectations than I thought, the movie is super entertaining.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
