Agreed. The idea behind Harmonious isn't bad, it's the execution which does just seem like Disney sung in both English and other languages.
Another thing I keep thinking about is how the expectation was that, even if the barges were ugly and you didn't like the IP element, the technology would be spectacular. Was it? Maybe it comes across in person, but it's hard to see the real wow factor of the screens with fountains, lights, and moving arms. The design of the barges and fountains still looks more odd than beautiful to me, even with things like the moving arms in action.
