Please stop the arbitrary hatred of MW3.
Yes, it's "popular".
Yes, lots of college guys, jocks, regular people and other "non-nerds" play it.
Yes, there are people who play MW3 who have never heard of Penny-Arcade and don't read review scores.
It's actually a fun game though. It has a polished, shiny campaign mode. It has a great co-op mode and solid multiplayer. It fixes many of the issues in MW2 and has the industry's first console subscriber FPS model, akin to GOSU TV for Starcraft. It's in many ways a title that besides leading the FPS genre, is trialing things that could completely change how FPS games are sold / function.
Yes, I know, I know, it has committed the grand awful sin of being "popular" which means "hate on it because it's just a MW2 clone greedy Activision"... but you might actually want to play it with an open mind first. If you can't have fun playing MW3, you have become extremely cynical and jaded... and that's coming from the most cynical and jaded person in System War's history.
