Kingdoms of Amalur: Reckoning. Not only a terrible PC port, combat was mostly spamming the strongest skills you have and insta-win. Not to mention so many pots you were basically invincible. Too easy even on the hardest difficulty.
Bioshock 2. The game itself wasn't bad, but GFWL is just awful. I avoid any game that requires it now.
Prince of Persia collection: It was cheap for all of them so I thought I'd get it but... I don't really enjoy the games that much. Platforming bits are fun but the combat is more annoying and ruins the enjoyment more than anything.
Winter Voices: This game tried to put everything into creating a story. It was interesting and I did want to know what happened but the combat itself was just... so bad it was unplayable for me.
Mirror's Edge: Controls were... completely unresponsive or just didn't register like I wanted. Character even somehow fell while ziplining. Just..no.
I can name a lot more games I was pleasantly surprised with however.
