The Amityville case, One of the most haunted paranormal investigation done by warren family. After the real Lutz family left the house, no more paranormal activities were reported. And that makes it somehow mysterious... what about all that mess? Lutz family leave and it's all gone? Something doesn't make sense here.
Anyway, let's get to the movie: it Had some improvement from the original version...Sound effects, jump scares, the casting, and specially the sound effects, I suggest you to use some earphone or something and max the volume. With every transition in scenes, you might jump out of your skin. The story was A little too rushed, and my guess is that it's because this remake and original movie were inspired by a novel and so, when you write a novel, that's easier to build every character's backstory but in movie they couldn't fit all the novel content.
Last word, it was worth a night to watch.
