Ahm. Pokemon comes to mind. Genwunners will always complain, but I don't think there's a generally accepted "bad" Pokemon game.
Is the Xenoblade series different from the Xenosaga series? I would say XBlade fits the criteria, but I dont know about XSaga.
2D Metroid is another one. Animal Crossing.

I think they all fall under the Xeno spiritual series, but I'm not 100% on that.

Though spiritual successors, the series are different.
