I felt captivated from the first scene, and only became more intrigued as the story line progressed. There were some satisfyingly, unexpected turnouts, and I loved that. However, the ending...I didn't buy it.
Overall, the plot made me think, and I could really feel for the characters. It's shocking to see that camps like this exist, but I feel that this film has definitely raised awareness.
Definitely worth watching. Plus, Mila Kunis is a beautiful woman to watch =)
