If waifubait characters are what you mean then that's lazy on the developer's part, but there's worse.

A lot of the appeal of a platformer is its character imo. Mario, Mega Man, and Castlevania have cool characters. I can't even imagine playing Nigger of Persia regardless of its technical qualities.
I remember when Braid was popular, one look at the character dispelled any interest (I still tried it out of curiosity and think it's massively overrated). Meat Boy was much the same. For some reason Spelunky, despite being kind of offputting looking too, was passable to me (it sure helped that it's one of the best platformers of its kind).
ADHD platformers are a curse unto the genre. Same with autistic precision platformers where you're expected to die a trillion times to get one series of pixel perfect jumps done in one flawless run. No. Just no. Celeste comes to mind as such slop (I hated it before I knew the girl was a tranny too, so it's not bias).
Yeah, Mario Maker proves that.
