Might be going pretty far back, but Tales of Symphonia's sequel on the Wii, Dawn of the New World is among my most hated games of all time. The thing is, I pretty much knew I wouldn't enjoy it as much as the first one with all that I had read on it and its details, but nothing could prepare me for the horribly irritating, unlikable, and pretty poorly-playing lead characters, the asinine menu-based overworld, the cheap knock-off excuse for the series' combat system (nothing flows, there's no technical application to artes, and returning characters have that ridiculous level 50 limit), and any aspect of the game that could even remotely be considered a step forward (like full movement across the battlefield) was completely outweighed by the aforementioned problems and thensome, and that's not even getting into how shallow the gameplay was made in order to push its awful monster mechanic. I honestly pity anyone who had started the Tales series with this game and is cursed with lenience towards it. It doesn't deserve anything but the dust its collected.
Another would be The Last Story. In my opinion, definitely the weakest game of Operation Rainfall. I found its linearity to be mind-numbing for an RPG, the gameplay seemed unique on paper, but in execution things eventually just become a matter of the player sitting back while the AI's do all the work, and all the extra touches to the combat to help liven it up really just feel clunky. The theme was one of the most grating cliche's around, most characters I found annoying, and the game's length is lacking. Where this game was pretentious with its attempts at supposedly "reviving old tropes" considering it really just accentuated what people hate about the modern JRPG. It's basically the fisrt half of FFXIII.
