Scott Cawthon's Five Nights At Freddy's is stupid and derivative and he doesn't deserve his success because there's not much to the games and the changes between installments are uninspired.
ZUN's TouHou is a work of genius and he deserves the fan following and success even though his installments are just reworkings of the original engine with some tweaking to the math.
If you don't like something, fine. You don't like it. But don't judge who deserves success or not, because the ones who truly don't deserve success are never the ones you target, just people who got lucky while you didn't.
