Exactly. The fact that Star Wars doesn't have as much cachet with young audiences as Marvel right now isn't surprising in the least. The sequel trilogy could have gone the route of the prequels and been a clown show, riddled with childish elements, shallow flash, and Jar-Jar jesters to trick children into paying attention -- in total conflict with the story it was supposed to be telling.
Instead, Lucasfilm has had the integrity to let the conclusion of the Skywalker saga be guided by a respect and fondness for the Original Trilogy and its characters. The sequels take the story that started it all seriously, and treat the OT's grown up fans like actual grown-ups who expect more than shallow power fantasies and insincere nostalgia.
Star Wars has plenty of time to reinvent itself for a new generation, after the Skywalker saga is over. Overhauling Star Wars to appeal to a young modern audience was never the task of the sequels. Lucasfilm has done what they could to capture that appeal, but respect for the OT was always paramount.
