In the end I'm not so sure that the "right" or "outrage" have anything to do with why Elemental failed.
One site listed ten reasons..... and they didn't even touch on the fact their was a minor non-binary character.
It just wasn't a great film.... Disney tried doing a Cannes closing debut for Elemental, and movie goers there just didn't like it. Now regular movie critics did give it a passing grade... but I expect it was lackluster enough that most will wait a few months to see it on
Disney+. Leaving them free to go watch something better at a very crowded summer movie season. I'm sure Spider-Verse was what most kids were interested in seeing...
