why people to much hate call of duty infinity warfare

Another one?

It's mostly a severe case of franchise fatigue, which started with Ghosts and is getting worse with every new iteration. That now really shows up even stronger with people preferring the remade older stuff over what's new.. Activision really should let this series rest for a few years.

Because it is cool to hate, and if you need to ask you clearly are not in with the cool kids.

Just pure stupidity, fanboys and some more stupidity.

To clarify i dislike both franchises because i am the ultimate hipster.

CoD died a long time ago, and they even don't care if people hates it or not (most of them will buy each released CoD every year - so, this is the only important thing to Activision).
Now, why the hate?
Simple, play CoD 4 and then play each game after that and you'll see there is no difference (except for some perk shit stuff or some cosmetic stuff).
And why the hate?
'Cause even with so many people asking for something new (I mean, not about the game (futuristic stuff is shit, at least in CoD series), but about physic, texture, etc); they keep making the same game. And another point.... all of us are done with one CoD every year.
