Why do people hate on Call Of Duty Ghosts

Probably cause it came after the so called "Goat" game, what I mean is that a lot of people loved Black Ops II so much, too much actually, dont get me wrong the game was amazing yes but people just nowadays have a lot of nostalgia about it and picture it as perfect when it wasnt. Call of duty ghost came out after Black ops II and it wasnt that bad of a game, I mean the multiplayer maps were very very bad cause they were huge and that broke a lot of the fast paced that call of duty usually has, and extinction has fun for a while but quickly became boring , the game had some problems but people hate it too much because it came after black ops II. Personally I find other games much worse than Ghost, like for example Advanced Warfare and Infinity Warfare, those two were just plain bad.
