I don't think this is a new stance or view from anyone really. The only reason to go to the land is to go on Flight of Passage (if the wait isn't too long) or to eat at Satuli. The bones of the land are there imo, but they sort of left off the special sauce. If they would add certain elements like I posted above, actually have followed through on the bioluminescence that was promised, or potentially a third ride, then the land would be be a bit better.
Part of what makes the land so average is that it feels dead once you're inside due to streetmosphere, any sort of interactivity (like Potter has with the Wand thing), or no M&G's. I don't understand why they got ride of the walk around mech suit or the drum show that performed in the land. I know it's not really realistic to expect walk around Na'vi (as they're very tall and very skinny), but something like the AA above would do wonders just to enhance the land on it's own and really make you feel like you're actually within the world that they were trying to create.
This temporary exhibit does more to place you on Pandora than the land at DAK does tbh in terms of recognizable creatures and characters from the movie. The most important character being them capturing the character of Pandora much better. I think part of the problem is that this is once again a timeline set land, set after the events of the films.
