I'm not a fan of the dome screens in FJ. They're to me the least seamless use of screens in any Universal attraction. I also think the Kuka movements could be better, it seems to me they tilt you back often just because they can. I get the impression they were relying on the Kuka arm to make it a thrill ride. I would prefer to see them used to move you through the physical sets in a more realistic way.
Kong to me like Gringotts, Spider-Man and Transformers is all very smooth and seamless. None of the technology is used just because, it's there for a reason.
