"The true story of a shocking crime and a secret that wouldn't keep"
An American Crime is based on the true story of some terrible things that happened to a young girl in Indiana in 1965 - and I do mean some horrible shit. Sylvia Likens is a young girl that is forced ( with her younger Sister ) to live with a stranger and her 6 children. The things that go on shorty after her arrival are reprehensible.
It stars Ellen Page ( from Juno ), Catherine Keener ( The 40 Year Old Virgin ) and has a script based largely on the court transcripts from the case. While I did have a few problems with it, none of which I can reveal with spoiling anything, none of those things stopped me from loving this movie...and hating myself for doing so.
Rent it, buy it, I don't care - see it.
