The thing you have to keep in mind about Hollywood is that in addition to Transformers, they do not have Escape from Gringotts, Spider-Man, or even Forbidden Journey yet. 3 of the best attractions in the world that also happen to be screen-based and all within a rock's throw of each other. So if they are impressed, it has to be weighed on a different scale at USH than UOR.
But what's more concerning is that the reviews really aren't very positive, which should tell anyone else to go back to the drawing board instead of recreate it at other resorts. Not that Disney is immune to this with the Toy Story Lands, that horrible new Frozen show, etc. but that's on a smaller scale.
Having The Fast & the Furious on the marquee is going to get people through the turnstiles in droves. That's a sure thing at this point. But is anyone worrying that it's any good? This has to stand the test of the time and it should help diversify the resort's offerings. For the Orlando resort at least, it would be more of the same.
