I do not like this! Not at all!
It's even worse when you realize what it looks like live:
I've been watching the game and it is very distracting. Especially when there is a different camera angle on the replay and the fake fans go away.
In other fake fans news:
lol Manchester City.
I will say, the fake crowd noise has been very good. It's improved since the return of Bundesliga in May. It sounds incredibly real. Not sure how it will work in other sports like basketball or baseball. However, I'm sure leagues in America can take notes.
