The movie sucked. It sucked more than a black hole about to collapse. As it collapses, "Gravity" increases to the point, it traps everything, even light. Nothing gets out.Not even Sandra Bullock could save it. I love her and will watch her in anything. However, great she and several other noteworthy actors are, they could not salvage this movie. The movie's plot had a great concept, but it was not developed into completed product. I do not need every sub-plot resolved, but this movie failed to resolve the most important component: what were the entities? Yes, at the beginning a character suggested they were "demons" but that did not explain why they only could control some people by seeing them. This story would have made a great "Tales From the Crypt" type half-hour short story. Best way to watch this movie is with a blind fold and sound muted while listening to the soundtracks of "Guardians of the Galaxy" 1 and 2.
