I thought Wanda's rune trick was pretty fun. I liked it. Her costume is definitely badass.
Definitely the fan theories didn't happen. We didn't see the Visions merge (yet), Dr. Strange didn't show up, Wanda (or Harkness) didn't unleash the mutants, and Ralph never made his demonic appearance.
What was there was pretty good though. To really complete her arc it needed to be Wanda that brought down the hex and freed everyone. And really, to face her truth and stop living in her disconnected reality.
It was cool to see her "become" the Scarlet Witch. As these things go, a lot was set up for future movies and series, as the MCU is just a perpetual stream of baton passing to the next thing and the next thing.
