Well before this gets locked...
Personally I dislike that due to them being so massively popular, other companies go out of their way to try to emulate Call of Duty. If everyone kept doing their own thing while Call of Duty had its numbers I wouldn't mind so much. Even the new ace combat is emulating Call of Duty (the developers themselves have said so)
The singleplayer is dull, with it being whack a mole where the enemy has perfect accuracy on higher difficulties meaning you just pop out of cover, get shot, then wait. Its slow and is boring.
Multiplayer is also bad. Leveling up in a FPS is completely unfair and ruins any chance of balance. A bad player can do better than a good player if he played longer.
The fanbase in general is also quite horrid, attracting many younger players, as well as what me and some friends call "Dudebros" who play nothing but Modern Warfare and think you are a faggot for playing other games.
