Rented this and played through it in two settings. Easily the most unfun campaign yet. While Black Ops annoyed me with its endless anachronisms and general unseriousness, it was a pretty good ride. MW3's premise is even more absurd than either MW2's or Black Ops (BlOps was absurd in a "cheap thriller novel" way, MW3 is absurd in a "bad fanfic" way), and it is far, far worse about telegraphing every "exciting" event about thirty seconds before it actually happens, rendering it instantly un-exciting. The most egregious example is the "Look at me daddy! Oh no I am dead!" scene, where you know immediately (even without the prior lame attempt at controversy) that the only reason that little girl is on screen is so she can be killed. The second worst example is in Hamburg, when you're advancing behind German tanks. What was the point of starting off that level with 30 seconds of being in a blown-up building before cutting to "20 minutes earlier?" All it does is establish that yes, the sequence you're about to play is going to get interrupted by a large, scripted explosion.
It really comes down the same most basic error a Doom level designer can make--when every key and every switch opens up a monster closet, monster closets aren't fun any more. In MW3, every helicopter gets shot down, every mission ends in an ambush, every rescue fails, every advance is interrupted with a big explosion, and if someone says "You've got to make it!" it means someone is going to die. At any given point, ask yourself "What would be the most cliched 'exciting' thing to happen next?" and now you know what's going to happen.
