Children of the Corn: Runaway is merely the latest sequel of a long-running franchise that had an okay first movie while this one was rather weak and, worse yet, a bit on the dull side which then turned into confusion.
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.
