The quick time events in this campaign were stupid. If they want to play a cut scene, play the cut scene. Hitting a button every 15 seconds does not pull me into the action of the cut scene. I do like the cutscenes where you can look around and whatnot (like the Jet level before combat).
Here i am watching a pretty cool cutscene and then i need to nearly drop my beer to hit the LB button.
I remember when CoD:3 started doing that stupid thing where you had to wrestle with an enemy and go through a quick time event. I thought it was stupid then and i thought it was even more stupid when it happened twice per level in this game.
Other than that, a very solid Campaign. My fav FPS campaign since MW2.
