True. That's a valid point. Both Potter lands and Carsland were really only 1 headliner and in the case of Carsland 2 C tickets and in the case of WWOHP 2 repurposed rides. In all 3 cases the overall environment was more than enough to overcome the lack of rides added. I think this will apply to Star Wars (hopefully) with this project. I view the Pixar side of the project to be more to add volume. However, if they fail to add at least 1 headliner type ride (D or E ticket) then it will be highly criticized by most fans (including me).
I really think the Springfield area was a nice addition, but if they put that into DHS people would definitely be more critical. It's hard to slam Universal for it when they were building so many other things. They get a free pass from most. I think that if FLE happened in 1995 or if WDW would have been building multiple E-tickets in addition there would have been a lot less criticism.
This is being built because Carsland was too expensive, correct? I doubt we'll be getting a headliner or two until whatever is done for SW is done. However, DHS needs more rides/attractions. Doing this first, doesn't bother me. The park is over-concentrated in headliners as is. If this addition looks good, we may truly have a Pixar Place instead of just one lone attraction. Criticism is more than warranted for the pace at which Disney does things nowadays. I too have the fear that this will be a simple, fairly straightforward project that will take the better part of a decade. By the time it is finished it could be Avatar all over again as we have constant fights over whether or not SW land is going to happen since the 9th movie has been out for 2 years.
