Just saw this today. Took my mother in law to see it. We all liked it very, very much. There's a lot going on in this film--a missing child, the audacity of the police, an innocent being victimized, a crime of terrible proportion, and a mystery. It's a really good film--not perfect; I think the second half meanders a bit, and the last line is VERY corny. However, the acting is superb and the film keeps you guessing. It's subtle (most of the time) and lets you draw your own conclusions.
I really enjoyed it and definitely recommend it. I give it an A-/B+
