Very cool premise. Original. That's rare. I appreciate that. But the movie itself was painful to get through. Hated every single character. Not one of them was reasonable for one second. Not one of them was anything but cruel to anyone else, eliminating any possible reason to care about what happened to any of them. After barely making it far enough to get to the point where things pick up, it was unfortunately very easy to tell how literally every scene would play out from then on. Just pulling teeth and waiting for the foregone conclusion. The personal loss being the motivation for doing all that bad stuff was tired and expected. I was skipping ten seconds ahead at a time towards the end because I needed it to be over. Nice premise obliterated by below average writing, bargain bin characterization, and zero reason to get invested in anyone's fate. Stick to directing, boys. Leave the writing to the writers.
