Is Lights Out a Horror Movie?

There's a couple of moments here where I thought they were building to maybe a twist ending that they didn't go for. It may be too much for some people, but for other people, it's going to be a great gauntlet. If you're a horror fan, you're really going to get something out of it. You're going to see something that's just exactly how to do this exact thing. However, it is really intense. So just a fair caveat for people who maybe are a little squeamish of horror movies,. There's a lot of really intense imagery in this a lot ofreally intense sound.
