There are lights in every corner of the house, and the electricity is on, but the film is so amateur that only camera light is used just to "scare" people. I don't understand people using only camera light and get scared instead of simply turning the lights on. It's even pitch dark near the door- while the outside corridor is brightly illuminated. The owner of the house doesn't need to turn the lights on when opening the door. Another vampire movie scenario would be more appropriate. Amateur, amateur movie.
A four-year old kid is hanging around and not even scared when things go real crazy- another big fail. There's no rational and sensational explanation of a four-year old kid walking in the house without even screaming and taking everything so natural.
Why does not the family move away ? This is another question the scenario-maker needs to answer. Yes the "haunting" is about the family not the place, but at least the family needs to try communicating to the soul and solve the problem, instead of hiring a crew to put cameras and take pictures of the house. A lack of rational scenario.
