Really enjoyed it.
Observations:
1. The series title should've been "Unprocessed Grief All Along" (just like Wandavision!).
2. My one quibble is that there were some things that I thought were really rushed at the end. It could've used another episode or two to cook, although I suspect that if it had, it would've been decried as "moving too slowly," so there's probably just no winning with a story like this for modern audiences. Still, I think Agatha's turn from "basically a bad guy" in the penultimate episode to "You should totally trust her now" in the final episode was...rushed. And I would've liked to see more of her relationship with Rio prior to her pregnancy, to help sell the connection between the two.
That said, it was a lot of fun overall, and had some fantastic acting. I'm also looking forward to seeing these characters in other Marvel stuff in the future. I love the blending of the weird elements of Marvel, specifically the magic and cosmic stuff. Grounded superheroes is fun, of course, but I like when Marvel gets wacky.
