The Killing Jar (Movie)

So I just finished the killing jar...intense and wild move; very twisted and morbid. It's about this run of the mill diner that takes place out in the middle of the desert (think of the movie Legion) looks like the exact same setting. This guy comes in and is acting weird, because of a murder that happened in the next county the whole diner is on edge. Assuming it's him the police officer questions him. He leaves then comes back in with a gun-taking the whole place hostage while slowly killing everyone off. I can't really recommend it as the acting was terrible, but for what its worth it has a few twists and turns in it that will deliver a decent shock value.
