This is a mystery movie. The plot is unoriginal as it gets. Some people trapped in a facility, trying to find why are they here, as they face an imminent danger. I like this genre and my expectations are not very high.
It was an interesting movie, never dragged. Not great acting, just sufficient enough to not distract me. As it progressed, it was getting better. There were a few surprises, even characters looked more interesting and likeable. Still, i wouldn't call it a good movie, but definitely it was watchable.
Then, a totally unnecessary twist happened that ruined the final 10 minutes. Sure it was unpredictable, but definitely not clever. Another big revelation happens in the final minutes that there was not a single hint before. For a twist to be good, it must have been foreshadowed before. This came out of nowhere. Lazy writing.
Not a bad movie and you will probably enjoy it if you love mystery movies and your expectations are low. As for me, i didn't enjoy it much. My expectations were not high, but this was pure mediocrity.
