Dar Salim and Jake Gyllenhaal were both absolutely amazing in this movie. This movie had me on edge almost from the beginning. I was sad, I was scared for them.... and I was angry about this situation. Jake's and Dar's characters had a bond that surmounted any challenge. I felt the emotions of both characters, especially Jake's. The pain, the sleeplessness, the obsession. There was a goal that needed to be accomplished, and that's all there is to it. If you're not gonna help, then get out the damn way.
