The first Wicked was an Oscar-nominated, well-received blockbuster musical for the ages, all results that retroactively justified the decision to distend one stage show (running time, minus intermission: approximately 150 minutes) into a pair of movies (combined running time, minus credits: approximately four-and-a-half hours).
The problem with the post-Lucas films is that they never quite decided what they wanted to be. The Force Awakens tried nostalgia cosplay. The Last Jedi tried to set fire to nostalgia cosplay. The Rise of Skywalker then tried to urgently stitch nostalgia back together again. The result was messy, divisive, and crucially for Disney almost impossible to spin off.
