Using the term Pixie Dusters makes you sound a bit immature about this whole thing. That kind of condescending attitude isn't going to win you any debates, and it certainly doesn't make you sound any smarter. In fact, you come off sounding overly defensive when you resort to using terms like Pixie Dusters, as if you know that Hulk Coaster feels like it belongs in a Six Flags park. And while I've never said that I don't need to go to Universal (both parks are great), Hulk does feel to me like it's been plucked straight out of a Six Flags. Same for Rip Ride Rockit. Neither of them do a very good job of theming to make them feel unique (same goes for Primeval Whirl @ AK, but I suppose it fits the conceit of Chester and Hester's roadside carnival). Hulk has no story, nothing to draw you in and make you feel like there's a reason for this thing being here. I like the coaster, but it's ugly and the queue and the area around the coaster are not very memorable. Dragon Challenge fares better thanks to the queue and setting.
NearTheEars explained the premise of the Toy Story coaster, which was covered in the press info and yesterday's presentations. The idea is that you've been shrunk down to the size of a toy. All of Toy Story Land at DHS is supposed to be Andy's back yard, and he's set up all his toys and play sets, including a toy roller coaster set, but instead of using the train that came with it he's using Slinky Dog as the train. It's up to the guest to decide if they buy into that or not.
