Forget comparing construction times, forget comparing Disney vs Uni, forget talking about how much of a thrill it will be or how attendance will be affected. IMO, the bottom line is that the 7DMT and New FL in general are excellent examples of how TWDC has become lazy and has somewhat lost the ability to blow your socks off and create something so incredibly original and immersive that it re-writes the standard others follow. Is New FL cool? Sure, but its not mind blowing. Its nothing Uni has to worry about competing with, its nothing that makes you want to return to WDW. Theyre still relying on attractions created 10 years ago or more to make guests return. Like the article said, it could have been a slam dunk, but they went for the lay up.
As far as Comcast fast tracking projects to make money, yes, they want to make money, but they are doing that while blowing your socks off at the same time. Disney used to know how to do that. (your post was great, just giving my perspective )
