Just watched this movie now that it's out on Disney Plus. Yeah, I really liked this! One of the better films; it's fun, interesting stakes, and a bit silly when it needs to be.
And more screen time for Wong. He's great. :3
That was my assumption. I think Rick and Morty use a similar concept.
I agree on this point. Though I wonder...
Spoilersince Dr. Strange had America with him, and she was what Strange needed to defeat Wanda, maybe the book technically worked (or it wouldn't have worked. Kinda an interesting thought).
