Florida's flight over London scene is still quite well executed. It could definitely do with some updates to paint, lighting and minor effects, but design wise it is still conceptually sound. The forced perspective effects in this scene used to simulate a gradual increase in altitude are still probably the best out of all the Pan rides around the world, particularly the use of more 3-dimensional buildings compared to California or Paris.
What they did to Tokyo's version is probably similar to what we could expect for a major overhaul in Orlando, given that both were identical rides originally and it would probably be easy to replicate the same changes. The layouts for CA and Paris are quite different, and Shanghai is a totally different layout and ride system.
I like parts of what they did a lot, and others i'm not so on board with. Again the refreshed paint and new effects are very welcome, but they kind of ruined the design of Tokyo's London scene a bit. They made a lot of the previously 3D buildings just a flat surface instead, rearranging some of the remaining buildings, and it negatively affected the forced perspective. The new Neverland model is also off. Again lovely new lighting and digital mapping effects (especially the star curtains on the walls which are desperately needed in Orlando), but there is something completely wrong and poorly designed about the shape and design (refer to California and Paris for comparison). The new Lost Boys, Mermaids and Indians are all very nicely designed visually, but they are too close together and the pacing is crammed. I am far from being a huge fan of the Neverland Island scenes in Orlando's either, but I would like to see some improvement to the shape and pacing of some of these scenes if brought over to Florida.
The scenes from Skull Rock onward are all fine, they really didn't change much. Just with some new lighting and digital effects. They could have actually gone a little further with some new effects here, as well as some better animatronics.
I still think Paris might be my favorite version still. Orlando still has the best forced perspective for London, but otherwise Paris edges out slightly over the others. Paris' fiber optic pixie dust effect on the Pirate ship near the end is still second to none IMO and looks amazing. I like the soundtrack in California and Paris better than Orlando or Tokyo too.
Shanghai looks fantastic as well, bit different but quite cool. My only real gripes are not adhering as much to the film's soundtrack (needs more You Can Fly) and the absence of the minor character scenes such as the Lost Boys, Mermaids and Indians. There aren't as many physical figures as a whole (though what is there is well done), more heavy on scenery and projections. Beautiful nonetheless.
