So for people who don't like dinosaurs, don't go to the Jurassic area.. people who don't like comic books, don't go to the comic book land.. gotcha.
And for those of you who don't like Dr. Seuss.. go to hell.
It looks to me to have a wizard/dragon theme, no? What is the theme of the comic book land? Or the Jurassic Park land? We are talking about a Universal park here, not Disney. Universal seems to just exploit movies and builds rides centered around them. I doubt people will be turned off by the HP portion of the park because of 'lack of theme', even if there is no 'learning moment'.
I do totally agree, and tend to lean towards the Disney parks for exactly what you and Robb are talking about.. but put in context, this land is just like everything else Universal has done at the park, and I think the theme of HP is equally approachable compared to the others in IOA.
