Bob's Quick Look - Sinister (2012)

In this film, Ethan Hawke plays a true crime writer seeking to reclaim his pedestal as a best selling author.  He moves his family into a house where another family was previously murdered and the daughter had gone missing - much to the dismay of local law enforcement.  In the attic he finds a box of home movies of not only that family’s murder, but the murders of other families from across the country spanning decades.
What begins as a mystery of murder and abduction becomes a walk along the thin line where the worlds of the living and the beyond converge. Ellison begins finding the same occult symbol and the image of a strange (what looks like a) man in all of the films and realizes the closer he comes to the answers he seeks, the closer he and his family come to joining the dead.
*Spoiler Alert* This is a good example of a movie whose makers should have been a little more careful about how the trailer was made. First, the trailer made the movie look like Ellison stumbles onto the demon early on, and the action of the film becomes a fight between him and the demon, Baghuul. While the supernatural elements of this movie come to light fairly early, the nature of the demon does not until much later in the film.
Second, I feel that it provides too much plot development which should have been left to the movie. Specifically that Baghuul was known as the 'eater of children's souls'.  If you come to the movie with this in mind, the second you learn about the missing children is when the ending of the movie becomes predictable, especially when it comes to a scene where the missing children haunt the house.
Disregarding the trailer, this movie does have a very interesting story.  I especially liked how the plot wasn't carried solely on the shoulders of the events of the murders and the haunting. Rather than being an event driven story with a cast of 2 dimensional characters to fill in the blanks, we have a character driven story complete with man vs. man and man vs. self conflicts with characters that are well developed and believable (which is becoming rare in Hollywood horror).  There are some good fright moments here along with elements that might make one cringe.
Try not to keep the trailer in mind, but I would recommend this movie for fans of supernatural horror and psychological thrillers alike. The R rating is for violence and a little language.
