It’s not good filmmaking to begin with, or at least not filmmaking that I find agreeable in any fashion. But when you add on the fact that it essentially retcons most of the plot of the original Wizard of Oz, and in doing so detracts from the original rather than enhancing it, I become annoyed. And when you add “the people love fascism and just wanted me to be a fascist!” to the list of wasted opportunities, I get angry.
In an attempt to avoid the extremely political plot beats of this extremely political musical (whether intentional or otherwise), Chu and Co have neutered it of any of its relevance to its time and place. Utterly dead on arrival.
We laughed at “if you’re not with me, you’re my enemy” in Revenge of the Sith, but we really didn’t know how good we had it with George Lucas. Today’s blockbuster filmmakers are spineless cowards.
