Self-categorized as a SciFi/Thriller? There was no science and the only thrill was when I got bored with the movie and watched a cat versus bear video on my phone. I watched this "free" on prime and feel like I was overcharged. If you want to walk away feeling like you've been cheated out of 108 minutes of your life, cue this one up. The only way this could get a 5-star review is if it is from a paid shill.
