I like Wicked. I would’ve preferred a single-movie version, but there is a lot of plot kind of rushed or skipped over in the musical. If they go back to the source material of the book they can flesh some of that out nicely and give more context to the story.
It might be good! It might be terrible. I don’t know yet.
But why hope for it to flop?
Edit, days later having seen the film: It was great, and I have essentially no complaints. Glad they split it into two, it would’ve been far too rushed as a single movie.
