Whether it was a different concept water ride or not, as I recall the plans had it both inside and outside the building. That's a huge change. Nothing in Pandora was officially promised when they made the announcement 5 years before the land opened.
I know they are cutting costs, but that still doesn't mean that I'm not correct in that these lands aren't being done "properly" or at least with due diligence. Heck, I won't even go into TSL as that's already been hashed out 50 times since it opened just over a month ago. I know we both love WDW but come on, admit that they've made mistakes even if the product is still solid. It's like if I've got a kid who got a B+ in my class...yes they did a lot right, BUT they clearly didn't do it all right, that's what these lands have been. Good, really good, just lacking here and there, which takes away from the completeness of them.
Heck, even NFL had to wait another year to open the 7DMT, which should've opened with the rest of the land.
