Cut out either the Mario World or Galaxy elements so that what remains can have more time put into it. Like IDRC if these movies wanna just be bing-bing-wahoo action reference-fests anymore, but at least *commit* to a theme. These two sources shouldn't be competing for attention in the same movie.
If you were allowed to go back in time and change ONE thing in the Super Mario Galaxy Movie, what would it be? BUT, you can’t change anything related Rosalina, cuz that’s too obvious of an answer! #TheSuperMarioGalaxyMovie
