As someone who has not seen PATF, I'll chime in for just a bit. The first time I watched this, I was confused as to what the story actually was, probably by not being able to understand all of the audio. However, I was very 'meh'.
The second time through, I watched it with my girls (12/10) and while I understood the "plot" better, I was even more 'meh'.
The third time, I watched it with my wife and she didn't like it either. All of their reactions were....it's boring and the story is lame. Not only that, but it took me at least twice through to understand what was happening with the shrinking part.
Like others, I will echo that it seems like it LOOKS nice, ala Navi, which I also find very boring, but pretty. However, this is probably going to be another one like Navi for me, where it's just not worth the long lines that will form, to actually sit through this more than once.
However, this saddens me for another reason that has nothing to do with the ride IP. Someone earlier in the thread was referencing modern Disney and their lack of 'caring' or effort. They've had THIS on the drawing board for 3+ years? Modern Disney management just doesn't see to be putting in the effort that decades ago made Disney...DISNEY. They just think that they can slap an IP on something and present a mediocre product.
