I absolutely loved this movie. No idea why the "critics" didn't seem to like this or give it a higher rating. I was hooked from the very opening scene to the very last and that's what movies should do. Generally I find Kristen Stewart to be a one-note actress, but she totally nailed it in this. Definitely some of her very best acting here. Matter of fact, every actor was outstanding in this. This movie was terrifying and suspenseful in all the right ways and at just the right times and not once did I find it to be predictable. The special effects were on point and the characters and story line totally believable. The TJ Miller scene definitely made me gasp and I won't soon forget that one. It had me on the edge of my seat all the way through, exactly where one should be. This will definitely be one that I'll watch again and again.
