Modern Warfare 2 - The last good CoD game?

Is MW2 really the last good CoD game before the series' goodness... *snigger*... Ran to the Hills?... I'm sorry. I needed to get a good Iron Maiden reference in there somehow.

Two sentences, one of which is a stupid (unrelated) joke isn't really enough to stimulate discussion, so I've locked the thread.

If you want to write up a longer thing in which you detail the reasons why you think MW2 was the last good one, that would be more acceptable.
