I thought the story was laughably bad until the end where it was revealed it was made bad intentionally.
I played the multiplayer for under 10 hours because I can't really get into it. I did think it was more balanced though as in MW2 you start off with poop weapons while everyone else has uber guns and attack helicopter bullshit and such.
What I liked were the visuals of the jungle levels and the explosive shotgun.
