As much as I appreciate people's desire to want a perfect product, the same people also need to see reality. All of those wishful thinkers assumed that Universal would do something about the hideous show building, that you could actually go up in the castle courtyard, that you could just walk through the castle at your own leisure, ... I even thought that the greenhouses would be enclosed (because it's ridiculous that they're open), but that didn't happen either.
Logic will tell you that having separate show for every person that wants a wand is a nightmare. And you thought that the line for Pteranadon Flyers was bad! By doing it this way, it becomes an attraction as well as a gift shop (which technically adds a new attraction to the land). If this thing is as good as people say it is, then watching the show should be a lot of fun, too.
