Final Fantasy IV because the story is annoying.
Almost every main character happens to sacrifice himself for the rest of the party, just to reappear a few moments later down the line. All other charcters cry and mourn in each of these moments so it makes you the player feel bad and sorry for the loss, but then the character suddenly reappears and nobody bats an eye. And this happens so often during the course of the story that it loses it's entire weight. Even the spoony bard does this. I just stopped caring after a while.
Oh, so now XY sacrifices himself, okay. Surely comes back sometime. Yep, called it.
Honourable mention is Final Fantasy I on the NES, half the game doesn't work because it's poorly programmed.
