It's definitely Spirit Tracks. I'm the kind of person who absolutely loved Phantom Hourglass and would have happily accepted more of the same, and I still thought Spirit Tracks was terrible. I'm glad this poll suggests people have reversed their opinions on those two because the consensus just after Spirit Tracks' release made zero sense to me.

Before I beat it, I would have said Zelda II. That game has one of the worst first impressions of any game I can think of, particularly because of Link's dinky little dagger that makes fighting enemies borderline impossible. Slog through it until the first sword upgrade, though, and the game is actually quite good after that point!
