I'm not particularly married to either side (I think Kenny and the Bucks are great in ring, but I also can see how their antics rub people the wrong way), but I wonder if sometimes we sound like the grizzled vets who complain the young guys are exposing the business and don't know how to work.
I tend to agree with Dave when he says that if something draws, even if you personally don't like it, then it works. If you complain about something that works, it makes you look out of touch.
I also think a lot of it comes down to everyone, smart fans and casuals alike, having to get used to there being a different style of wrestling in a major US promotion for the first time in decades. We've all been accustomed to things being Done A Certain Way for so long, seeing someone do things differently appear alien even if they are succeeding because there's always that hind part of your brain that is like "that can't be possible, they didn't do it this way".
