It's a whiz-bang action show. There will be, without a doubt, people complaining that it is another screen attraction. And it is. But the use of the screen is so unique and just plain cool, that I think it will be limited to deep dive discussion boards like this one.
That said, I think it solidifies that USF is the projection technology aka Skreenz! park. That's ok. USF is the "OMG! Skreenz!" Park. IOA is the "OMG! That Track is Naked!" Park. And Epic will be the "OMG! I Can't Believe I Have To Go Back To The Hub To Get Anywhere!" Park.
