This movie was awesome. It was extremely tense and well acted. The little girl can hang with any adult actor. Ive seen her in some kids movies that my daughter watched but here she shines and has a bright future. The Duffer Bros went on to make Stranger Things so i am not surprised to find this little gem on their resume. Some people say it was slow. They want to watch marvel crap with cgi explosions every 3 minutes. Do not read any reviews with spoilers because its better to go in blind.
