Resident Evil 6 and Hyperdimension Neptunia (the original PS3 game) are probably the most qualified mentions for me here. I didn't think they're great or anything, but I liked them. I'm pretty sure the critics and fanbase both don't think much of these two.

Honorable mention: Ar Tonelico 3. While not as good as the others, I still thought it was great. I'm not entirely sure how the fanbase sees this entry but critics were not afraid to be harsh to this one.

re: Star Ocean -
I dunno if I'd call Star Ocean 3 or 5 hated, 3 was pretty well-received apart from people who were upset with the game's big twist, and 5 isn't so much hated as just a big "meh" from everyone. For the record I liked both of those two (5 a bit less due to some disappointing aspects), I didn't like 4 though, despite finishing it
