I think it's pretty obvious why. I'm personally not one of the people who disliked the video. In fact i'm working on a video right now to explain why i think it could end up being a fairly decent game.
But the COD Community has been calling out for a classic Call of Duty game (WWI and WWII era) for a while now. I've been seeing petitions and videos all about it ever since ghosts came out. But ever since COD stumbled on the futuristic warfare and boost jumps, they simply never looked back.
In a lot of cases, i feel like the video is being majorly disliked not necessarily because it looks terrible, but rather because fans feel like they aren't being listened to. Because they want that "Classic COD" game that has been talked about.
The reality of it is that one way or another, Call of Duty eventually has to innovate. Content creators for the game just want to see how far they can take it.
