Cusack's performance
I just wasn't buying it. The movie wasn't that bad, but he's just not that convincing in very serious roles. He's better suited for light dramas or comedies. Not suspense flicks like this one. If someone else had been casted, this movie would've been much better.
I did like Dallas Robert's performance. He was cool, calm, and twisted. Not over-the-top crazy like most insane abductors. He was great.
