Having gone into this film not seeing any trailers I was quite excited, however I wasn't blown away, it was an OK movie, the lead actresses fall into madness was convincing, however I thought there were a few tense scenes where you expected something to happen but then nothing, (SPOILER ALERT) I also totally saw the brother twist coming a mile away, I thought they could of done more with the ending with the husband, and shown the hospital attack scene back on the cctv to shocked onlookers who thought she was crazy, ie her police friend. The husband was never really proven to of done anything either, I liked the twist with her though, although it wasn't a great shock. Overall I did enjoy it though.
