Query: One of the better horror movies

The Campbell family moves to upstate Connecticut so they can be closer to a hospital. The families son is undergoing cancer treatments in the city. After being there a little while they discover that the house is haunted by spirits. They also discover that terrible acts took place there. A medium channeled spirits, and the spirits are out for revenge.This is one of the better horror films I've seen. I'm a fan of the genre, and I've seen a lot of bad horror movies. I was surprised with this one. I think that it having a true story behind it makes it more powerful. The production is well done. This movie has good actors, special effects, and some good drama. It's a pretty good film. I think any fan of horro movies can appreciate this one.
