As the title explained, yes, this movie is gross. It has a very explicit sex scene and it is very scary. I watched it, but I don't think I should've at 13. Other than that, this movie is great. It has very normal characters in a realistic setting until everything goes wrong. And gosh, the more and more this movie goes on, the scarier it gets, until you are at the very end holding your pillow tightly like it'll save you from this unholy twist. If you are going to watch it, just a word of advice: Kids, don't watch it with your parents and parents, don't watch it with your kids, cause it's gonna get awkward. The sex scene is very important to the movie and you won't get the ending unless you see it, so don't fast forward. Bottom line, if you don't think you can handle it, don't start this movie at all. I'll give it a 4/5 stars and really think about what you're getting into if you are 15& under. Hope it helped!
