First of all, the acting is fine. I don't understand why IMDB reviewers love to jump on bandwagons and parrot each other like birds in a forest, but the acting is FINE. Some of the actors were obviously more talented and experienced than others (the mother was a clear standout), but everyone did their best and were believable, for the most part. The only really rotten apple was the titular child, Rose. She is not very talented, and delivered her lines with all of the aplomb of a grade school production of Hamlet. So, the reviewers criticizing the acting are either just being nasty for no reason, or just want to add another penny to the pile. Don't even bother listening to those people.
As for the movie was fine, nothing to really call home about. It wasn't scary, the special effects were a joke, and the script was as simplistic as it gets with nothing even remotely unique happening. But the final act came out of left field, tied everything together, and made a truly mediocre film watchable. Let me tell you, those last 20 minutes had me INVESTED in what the ending was going to be. For that alone I bumped my review up 2 points.
The real horror in this movie can be found in the horrible parenting on display. You raise a son to his college years, fill his head with all of these delusions of grandeur because he's good at throwing a ball, and wonder why he behaves the way he does. Bad parenting is scarier than any Hollywood monster could ever hope to be, because it CREATES those monsters. Teach people to do their damn jobs as parents and so many of societies issues would disappear overnight.
That being said, movie? Mediocre.
Ending? Worth the run time.
Scariest thing about the movie? Entitled teenagers.
