Good story, Not enough for a whole film

It's complicated... I really like the directing, acting and writing but, there are issues with the way it's shot that I just can't deny. As much as I love the storytelling and the fantastic performance but, there are also certain scenes that didn't need to exist.

As somebody who had not heard any of this before, it became a curious phenomenon to sit and watch a film and slowly have the realities begin to click into place.

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."
