There have been a lot of really bad movies listed, but I promise you this is worse than any of them. I mentioned it somewhere here in the past year because a coworker told me I should watch it. When I later threatened to murder him over it, he backpedaled and said he never claimed it was good, he just thought I would want to see how "disturbing" it is. No, no I didn't.
It even has Danny Trejo in it. For about 3 minutes. Even he just wanted to collect his paycheck and forget this movie ever existed. I challenge anyone to watch this (it is free on Prime) all the way through, because the movie itself is completely fucking terrible, BUT THEN they do an M Night Shamalamadingdong twist at the end that is just fucking bonkers out of this world.
Unless you've watched this movie all the way through, you have no idea what truly terrible is. I would put this movie up against all comers, and expect it to win in a landslide every time.
