Oz the OG

2024.11.30
I watched Deadpool & Wolverine - there's a weird line:
"With the whole multiverse thing, it's not great.
It's just been miss, after miss, after miss.
Wizard of Oz did the multiverse first and they did it best.
The gays knew it, but we didn't listen."
So, there were the books, an early b+w movie, THE movie, The Wiz, Return to Oz, and Wicked. But is it really an exemplar of a multiverse?
