Yeah yeah, 1991, 1980, 2020, might as well all be the same year.
Anyway, no idea why they made dinosaur land a flintstones ripoff that was a real left-field kind of decision. The budget slashing is absolutely to blame, shows like Captain N that had some particularly shitty animation as well. Was the faceless Indiana Jones from SMB3 or SMW? Faceless Indy was particularly egregious and to this day I have never confirmed if that was intentional or if it was truly an episode-length blunder.
I'll take 100 animation errors over a virtue signaling any day, though. Be glad we don't have to see any "woke" Mario shit any time soon, because Nintendo's fully closed out from letting most of their properties be in purely visual media for probably ever.
