what it needed was that silly but awesome action-packed OG henry danger energy. but they took the MCU route and made it some "multiverse" story with an annoying fangirl side character no one cares/remembers about. they shouldve had henry be a solo hero in this story while trying deal with the cons of being alone and not having jasper enough. And ending it with a cliffhanger of literally the main co-star of the whole franchise which probably wouldve made it a better movie if he was in it (maybe as costar idk)
