If you are in the mood for a disturbing, depressing film with a hint of the bleak atmosphere devoid of hope of The Vanishing, say, this is definitely one to watch. The depiction of how people respond in desperate situations feels disquietingly true. If you are feeling fragile or depressed it is probably best to avoid this one until you are feeling stronger. Definitely don't watch if you are a nervous parent. I can tell that Prisoners is a very high quality film, and the subtlety of the performances is excellent, so I understand the rave reviews it gets, but it was way too disturbing for me. Not enjoyable.
