Quoting Morris Schæffer (view post)
Mostly due to it not having aged well, and being outdone in just about every way since its time.
I've never been much for vehicular action to begin with. Without the insanely cool presence of Furiosa in Fury Road, or the shocking violence and sadism of Toecutter in the original 79 flick, it's just a bunch of car chases that are...decent, I guess?
I also found the group of good guys holed up in the camp to be pretty terrible. They felt like they were from a different movie all together, like Logan's Run or something.
