i be skeptical before go to this because of the horribly assemble trailer which make it look like an equally horrible movie . i be nicely surprise by how much i do not waste my money . i believe the film success come from how creepy it really be and how the environment of the house be . little thing like the sensor light create a true uneasy feeling . the shadow and ominously cold feeling of the house make it easy to tell that no matter how much you know horror film and anything could happen in the film . the acting be by no mean perfect and nor be they bad . the main character be convince even give the annoy teen drama that surround her . in the end and i be thoroughly impressed with the film in most aspect . it be definitely a film i would recommend .
