I loved the piss out of Modern Warfare (the first) for the online, and I still hate the single player. It's miserable. The story? Yeah, there are some fun moments. But they're few and far between. I loved the gilly suit mission, for instance, but hated the FUCKING FERRISWHEEL. The fun bits were interspersed among infinite frustration from neverending swarms of durka durkas. If a shotgun blast to the head does NOT kill your enemy, there is a problem!
