Why are so many Call of Duty Ghosts bad?

I'm currently playing CoD Ghosts on the Xbox and find the graphics mega. I think the story is not bad either, but I always read that it is hated, at least for the PC players because of the bad graphics and that you just die too fast, and so on, it is the first time that I play CoD but myself can't imagine that the other parts should be so much better, especially the graphics, because the at least the Xbox is bombastic and very realistic.

Other games have clearly a better graphics, Ghost was in his time a good graphics but you have already gotten it, I myself found Ghost well so did not go too well not too bad. But I can highly recommend the new cod (Mw), I've already downloaded it and can't wait anymore.

Ps: Everyone has their own game flavor, some find Ghost bad, some good…
