JRPGs definitely did get dunked on sometime within the past couple decades. There was definitely commentary going around about how JRPGs were somehow bad because they’re too linear and tended to have too many similar story tropes/character archetypes and random battles were bad, yadda yadda. Some people even speculated that the genre was dying out. (That prediction obviously turned out to be wildly inaccurate.)
I guess it could be argued that some people did dunk on it for culture-specific reasons, especially for the anime art.
