See, I think this is a bit of a misconception in the theme park world. Universal's parks are not nearly anywhere near what I'd call thrill seekers' paradise. Outside of Dragon Challenge, Hulk, and MAYBE Rockit their rides aren't really over the top thrills.
What Universal has set out to do, IMO, is show that they are the place for families with tweens/teens. The rides are still accessible and not overly daunting. They are world class, state of the art dark rides. Not thrill machines, IMO.
