As I am young generations, I can talk about the fast-cutting of nowaday films.
I have to say, fast-cutting really makes a film a "hit" feeling. Visually it did make the movie looks more paced, more "impact". And yes that definitely can make us young generations shout out "COOL!" or something like that. But the problem of that, (even I as a young man can see) is this technique cannot be second-thought. First time it may be cool, but if you think again, you will find it's useless, it's boring and there is no sense at all. It is not a thinking that this technique is good and unique for this film, it is not well thought but "everyone's doing that, why not us". No mind, no enough thinking is put into the film. So yes, may be when the film come out, we(as young people) will say it's cool. But after a little 3,4 years, no one will remember it.
And what worst is that, these non-sense, these "fuzao", makes people who watch them, listen to them, "fuzao" too. Many people will not pay much attention to the details even you did put your mind into it. Many people will find it strange if you do not act same as other "fuzao" musicians and directors. They will simply think you are not right. I really hate this. People won't try to feel the arts, they will only see, only listen to the representation. They won't try to see the soul.
So may be that's why people like these guys. creating music without soul. Because they won't see it. But on the other hand, they have to feed them without delay. More, more, more. Or, people will forget these guys, completely.
