I actually didn’t think Death Race: Beyond Anarchy was bad, just a bit more of the same from the reboot franchise, though switching things up making Frankenstein an outright antagonist or extreme anti-hero.
Death Race 2050 might not be very good but the filmmakers weren’t trying to make it very good and as a throwback to the 1975 original it certainly does the job well. That said, watching it solo, it wasn’t all that fun with the gimmick wearing thin early on but I suspect if you watched in a group, there might be some entertainment value.
