Don't know if it really counts since 1) I'm not sure how "niche" it is and 2) I don't really hate it, it's just that I'm a big frustrated by it and don't get the hype. The Ace Attorney series bugs me. Yes, I guess I like them, they're interesting enough and the trials can be fun, but there's few characters that I actually found interesting, everything besides trials is insanely boring, while the trials themselves are either so obvious I could tell how the case would end three sub-chapters earlier, or the˙ require such moon logic to solve that I don't know how Id do that without a walkthrough.

And OMG, the puns. Why.

There's also Breath of Fire III that I never got why people loved so much, especially over IV. IV was colorful with a rich story and complete character arcs, III looked bland and its story felt very rushed, to the point that I felt it fell apart near the end.

And yeah, Super Mario RPG was good, but I don't get why the Internet reveres it so much. There have been better Mario RPGs since.
