There is so little plot advancement I couldn't wait for this to be over. The acting is good at times but the plot just stagnates.

The parents have no depth, the cop is unlikable and there are basically no redeeming qualities to any of the characters except Joy's patents that see that things are going to far with the investigation.

The antagonist is not at all interesting and the depravity of the treatment of suspects is sickening. There is some exposition there that ties into another bit of the plot but that is not really explored and so there's nothing compelling about the discovery.

All in all a very unsatisfying movie.
