I don't think the majority of posters here mind legitimate criticism of the WWoHP. The problem is that many of the critics, including the DisUnplugged at times, are lobbing unfair - and sometimes untrue - criticism. When you just take one small thing, like the guy in the Slate.com article saying the owls don't move and that's a sign of Universal not caring, and compare it to reality that can be proved - that the owls DO move and move in different ways - it's hard to take everything else he says seriously. Is he deliberately lying? Did he go in with the Disney Would Do It Better mentality and just look for things to attack, even if they weren't there? Only the author can answer that.
I don't even understand where the Disney Would Do It Better mentality comes from, unless it was from people who hadn't been to Disney in over a decade. Many of those in the know, including Jim Hill, have reported all Disney wanted to do with Harry Potter was make it an interactive ride/game like Toy Story Mania. And even if they were to be convinced to do a whole land, it would be most likely be filled with "hidden mickeys" and sponsored by Coke.
