Fixing Sky High

Will should start the film with both his powers. This makes his journey one of learning that your character matters more than your powers. It also allows more time for a rivalry between him and Warren (who would be tearing down a nepo bully, rather than a powerless sidekick) more tension with him and Layla, and more falling in with Gwen.

The sidekick plots add basically nothing to the show, since halfway through, Will switches to the Hero stream. All it does is waste half a film's showtime on a discarded story and leaves you with half the time to develop the nuances of Will getting to know everyone and then choosing.

The sidekicks need no more intro than the powers audition and one clip of Will brushing them and Layla off in the cafeteria. And Warren desperately needs development.
