The criticism, I think is more to do with the backstory being weak or more likely why a solid backstory is not portrayed in this ride. It's been said by others that once you pass the ride's entrance, Alpha Centauri Expeditions up and vanishes. Why does that thematic story element suddenly vanish? Why are we as visitors of Pandora on this Na'vi boat ride in the first place? Why is Alpha Cenaturi offering the experience to us?
So we have a boat ride on Pandora. Now what!? Shouldn't the logical progression of the land and NRJ's backstory then become; ACE presents us with a tour of a Pandoran river. I think that is what is missing from this ride. There is a lapse in backstory, the narrative component. The big Why. We get a Show but no Tell.
Surprise! It's Nahtatour.
Without a narrative component the ride is simply a gentle boat ride looking at bioluminescent flora with a Na'vi shaman at the end of it. It's a very short, glowy headscratcher. A nice detailed ride but with too many open-ended questions. What is it's purpose beyond looking pretty?
Show don't tell is the goal of good writing.
I am honestly flabbergasted by the over-analysis of this ride. Mo'ara is mostly ACE. The ride is taking us into the Navi part of town. We get to compare and contrast the difference between those two peoples. I think Disney has described it quite honestly. Beyond that, Cameron called it dreaming with your eyes wide open. The whole thing is based on a dream he had when in his teens, one that stuck with him. Even from the videos, I feel it has captured a sense of lucid dreaming. What's wrong with pretty? It's actually harder to pull off than careening action or loud explosions. The ride seems like a high end meal. The portions might be smaller than at the neighborhood sports bar, but a lot more time and talent went in to it and it's meant to be savored not devoured.
Have you ever gone canoeing? What is the plot of that? Guides are nice, but so is exploring on your own. Here we get to cruise though one of the most beautifully realized dark rides ever. The closest comparison I can think of is if someone took you on a cruise to see the northern lights. Sure you might want to know a bit about the phenomenon, but when you're actually witnessing them I think you'd want peace and quiet so you can experience it on your own terms. You may not even like it, but the earth claims seven wonders and at each and every one of them can be heard the phrase "that's it?"
The ride doesn't have much plot, but it does have a progression. Except for the winding boat path, the first half gives us total freedom to look and listen. Slowly, music comes in. We see a procession of Navi and beasts. Where are they going? Seems we picked a special night to venture out. Then we meet the Shaman. She engages us directly, a momentary touch point amidst the aimlessness. The sights, sounds, and song is all beautiful. We don't know what she saying as her language is not ours. Does it matter? Do we need an interpreter standing beside her? Somehow, I think everyone gets the sense that she's singing about harmony.
Old school Epcot Center attempted edutainment- it held your hand and gave you linear history lessons capped with brief moments of speculative fiction. Animal Kingdom strives to be the true discovery park- I'd say it ALLOWS more of its guests. Sure there's lots to learn, but isn't the best part of the safari when the guide shuts up and turns the radio on? Both strategies have their place, but for varieties sake, there should be a place for both.
