Tomb Raider (the 2013 one) - Too. Many. Damn. QTE's. On top of which I can't stand the constant unending cutscenes every 30 seconds in which Lara Croft keeps moaning on about how shit her situation is.
Hitman Absolution - Loved 2, 3 ,and Blood Money. They fucked up the disguises - which was the best part of the Hitman series - in Absolution.
All GTA games after San Andreas. Been playing GTA since I was 6. Probably played around a thousand hours of 3, Vice City, and SA combined. They seriously fucked up the stuff that made GTA so fun in the first place from 4 onwards. 5 did fix some game mechanics but the game characters were fucking terrible. I really enjoyed 4's story though.
Far Cry 2 - Does anybody enjoy playing a game where EVERY SINGLE ENEMY OUTPOST respawns every 15 seconds and shirtless African dudes take 1 magazine each of AK rounds before dying on the easiest gameplay setting? Yeah, me neither. It's actually a shame, though. The game is really beautiful.
Ass Creed III and IV
The Total War games
Dead Rising games
Dead Space games
And my most hated of all - Bore - derlands.
