I don't mean to get into the middle of the discussion, but the attitude area didn't always have great booking, true. It did, however, have way more optimism and gamble booking. It played with tons of ideas and that's part of what made it so great. Vince had no choice back then but to go with what worked.WWE has never had particularly great booking cross field. Vince works his way, he doesn't care if we don't like it. He books what he likes and that's it.
Not even the heralded attitude era had good booking from top to bottom. A lot of it was mediocre or okay booking brought up by hot crowds.
Now a days, and in the words of cm punk, the WWE will make money in spite of itself. He found a system to keep the cash flow still coming and keep him as #1.... So why stop? I mean unless another competitor comes into play or Vince truly starts to not sell out arenas, the same repitive, not creative booking will happen.
