It seems I was wrong in the Death Race 2050 review to call the reboot series a "trilogy." While it has been called such and marketed as such for quite some time, in 2018 a 4th movie in that timeline was released. Death Race: Beyond Anarchy. This time around, the prison is less a prison and more a dystopian wasteland, that happens to be a prison. There's a death race going on, and people are interested in winning it for (blog post) one reason or another. Most importantly however, is that I had to be careful to edit (blog) around a TON of skin.
