I know this thread has gone off the rails a bit, but even with all of my negative impressions, I wouldn't go as far as to say that 2D Kong is as bad as Supercharged. That feels to me like just plain hyperbole.
F&F is a laughable effort with corny stilted acting, lame setpieces, and a bulk of the attraction so needlessly abrasive and loud that neither myself nor my SO can comfortably ride through without a pair of ear plugs.
Kong, even without 3D or the outside entrance scene, still has some legitimately rather cool practical sets with the Kong skeleton, Bat animatronics, Kong himself, and a few screen scenes that are paced well, action-packed, and well-synced with the water effects and motion profile. It's a solid ride with the 3D, and without it, I still argue it's fine. Just not anything special at all, especially considering the long wait times it's known to amass.
It's Minion Mayhem-tier for me. It's fine, and actively worse without 3D; but the reasons why I think that are only really because I'm a diehard theme park nerd and I care about little things like the weird artifacting that the running Dinos have during the Kong 360 screens. Universal has the budget to fix that, I notice it, and I think they should work to make it better. It's also worthwhile to point out the experience of the random 50 year old dad in the party in front of me, who went from stern face bored in the queue, to sitting upright on the bus with his face all lit up, smiling and laughing along with the ride video and telling his family "This is so cool!". He had no clue he was missing anything, and that might be why we won't see the 3D come back here, because he had a great time regardless of the weird artifacting or visible seams or wonky parallax. And frankly, good for him.
