The movie had a gender fluid character and it tackled "racism" but I did not know it from the trailers. My kids simply did not care about it in the least and neither did I.

And here lies the problem with the movie, it was just a medium for propaganda with no interesting plot. If you looked at the trailers you get a setup of a city full of elementals and that there is some romance between pathetic water dude and the fiery girl, that is it.
