That would be a very strange perception indeed given how much they've already changed the it.
Perception is personal, so I don't think I could judge it as "very strange" considering I feel like Mission BO, Incredicoaster, Stormrider, and even Frozen Ever After are all mid to low-effort rethemes. They all have changes and work put into them, but the work doesn't seem to be to the standard that Disney gives to creating new attractions.
I would say that we can all agree that Disney hasn't put in Maximum Effort, but I think some folks on here would even argue for that perspective. One that I do not understand.
For me, TBA and what they shown us feels like a house flip. The outside looks the same, just without some of the iconic features and updated landscaping. The inside, from what they have revealed, seems to be very similar with just darker lighting and fewer AA's.
The new AA's do look fantastic so maybe that will change the perception when actually riding it, but FEA has some decent AA's standing around bland sets and pushing a storyline which feels lazy and one-note.
I hope TBA is a great success because it isn't going away any time soon, so I'd rather enjoy it than have another ride I tend to skip. But Disney hasn't been doing a great job in conveying information to feed that hope. At least, in my opinion.
