I have many many problems with CoD's singeplayer approach.  If you play it on anything harder than normal it is ridiculously tedious, and not fun at all.  It basically ruins the experience/atmosphere because there is always only ONE way of approaching each situation, and if you fail, you just have to do the same thing over and over in a senseless trial and error process regardless of your skill (continuously respawning enemies? => cheap solution instead of programming good AI).  While the singleplayer mission presentation, scripting, graphics (kinda), and polish are impressive, there is virtually no replayability due to the highly linear gameplay approach.  If it weren't for the multiplayer, I would never have a reason to put the disc back in my xbox after finishing the campaign on veteran.
