Forum:Call of Duty getting sad?

Does anyone think the stories of Call of Duty are getting kinda sad? I mean the obvious answer would be that there trying to express how bad war is and the tole it takes. Also seeing Woods as an old man in Black Ops 2 is kinda sad, especially him seeing a war-torn world (I think it would have been cool to see him been frozen in a block of ice or something and refrosted but I kinda got that from Captain America). It just makes you think damn the world of call of duty is so morbid, ofcourse it's no game for little kids so you can't expect it to be holly jolly. So what are your opinions on the matter people?
