Bug Riders. Thought the game was okay and the lore was pretty neat; apparently others were not so kind. It was a 3D racing game riding giant flying bugs on the Playstation, so the ways it could go south are probably pretty clear. It felt like they crammed a fair amount of world/character description into the game's manual, though, made somewhat more interesting by the fact that most racers were royals in charge of a specific province. One was highly skilled but completely arrogant, for instance, so the king shoved him into the useless desert province to teach him humility, whereupon he immediately turned it into a thriving pirate city and learned absolutely nothing. I think another was given an already-thriving area to teach compassion which also failed, and so on.
I don't think it was ever actually considered bad by numbers so much as by volume, but I did play Morrowind, then play and prefer Oblivion. Most of the legitimate criticisms (less interesting via more familiar world, hampered spell/enchant/alchemy shenanigans) struck me as understandable choices or necessary sacrifices, and a lot of the more subjective things (dungeon layouts) I either preferred or didn't really mind. And, of course, the game was just technically and mechanically better, having benefited from technological improvements and the possibilities that came with it.
