This was actually pretty good
I had no idea Kate Bosworth could portray the level of sheer evil on display here. She was creepy as hell. Almost terrifying. Solely because she never really loses her composure. She always keeps the performance just a tad shy of the trigger going off.
Wes Bentley's acting was also impressive.
Some of the music was a little weird and the film was not without flaws but it definitely kept me on edge and fearing the next sadistic torment on Bosworth's character's behalf. Additionally I wanted to know just what the hell was going on.
The reveal at the end was definitely a surprise. At the very end - I think Bentley's character was given the best possible outcome given such grave circumstances.
