This was a simple story with a very likable leading man. His 'regular' demeanor was refreshing and made him quite likable. I felt for him. He was in over his head and was just doing the best he could. The relationship between him and the female lead never quite jelled for me. She gave a good performance. She reminded me a bit of Zooey Deschanel. That, "I don't care" attitude, which worked for this role. And it made her turn at the end plausible. She gave a solid performance.
The overall film held my attention and kept me wanting to watch to see what would happened. I think a thriller is a hard film to make and Peter O'brien did a good job of keeping things moving and making the audience feel off balance as we wondered what nasty thing might befall either character.
