I will give you that one. Other than the irony of "greed will not pay" at Waltb Disney World, that was a wonderful use of a Disney song with an Epcot message. And done in a reflective and impressive way.
While on the surface, it's ironic, I don't necessarily think that it's ironic that a team of potentially idealistic (and likely underpaid and possibly exploited) creatives created an optimistic viewpoint. Even if the suits did mandate the song (which they definitely didn't, but theoretically, if they did, that would be undeniably ironic), I don't necessarily think it's overtly bad to have a positive message to the millions of people who may return home with a slightly altered perspective.
Disney has positioned itself as one of the most influential entities in the entire world, and many outsiders have taken note of that position and villainized it, but Disney's potential positive messaging impact far outweighs any potential fiscal impact (that's not to say they shouldn't have a positive fiscal impact, but that the Disney brand itself really is its most important asset).
As a result, while it may seem silly, especially from an outsider's perspective, a powerful show like IRoE, which sits in the center of World Showcase, a symbolic gathering of people, cultures, and experiences from a multitude of nations, is so crucial and even has a broader impact.
I am completely incapable of objectively analyzing Harmonious, or even Epcot Forever because, for me, nothing will ever be IRoE. I've said goodbye to family before their deployment following "We Go On" reverberating through the crisp lagoon air. The last night I ever spent with my uncle was under the whipping flames of IRoE. After returning to Epcot after his passing, the night no longer reminded me that "We Go On," but IRoE transcends entertainment for its personal significance to me.
That said, I did thoroughly enjoy Harmnonious. Some segments were purely chaos, but others like the Mulan segment were visually and audibly stunning and powerful. As for the Someday sequence, the Hunchback theatrical soundtrack that failed to reach broadway is one of my most streamed albums, and my god it's gorgeous, so my personal affection for Hunchback, someday, and the general sequencing also makes me love the overall segment. Other areas of the show, as others have countlessly stated, were simply overloaded. The show itself wasn't irredeemable, but its day views were, so I am very glad its removal is coming quickly, rather than the decade+ we were expecting.
As for the future, recognition that Harmonious wasn't acceptable makes me optimistic. Hopefully, this spawns a change worthy of Epcot, because Epcot is a special place, just like IRoE was a special show, and this presents a special opportunity to make something incredible.
