I quite enjoyed. As others have said, this proved to be much more of an Ant-Man & the Wasp than a Civil War... and that's totally fine. One of the biggest tendencies of the fan base is that we go all Zack Snyder on it and assume "this movie will tie directly into that movie, and this one will have a cliffhanger, and these two will share a villain." All the while we forget that WandaVision is about Wanda and Vision, not Doctor Strange or the X-Men or even the multiverse. It's about grieving and growing. All in all, pretty self-contained.
That said, it might also be like Age of Ultron where we look back and say "this set up Monica Rambeau for CM2, this set up Wanda for Doctor Strange 2, this set up two key parts of the Young Avengers, this brought Vision back" and see 5 pretty big chess pieces coming out of this. Thankfully, Kevin Feige is much better at keeping the stories focused on themselves while creating connective tissue.
I loved:
- that "Quicksilver" was just some dude. I think we can officially put all versions of Pietro to rest now. Wasted opportunity in the Age of Ultron, for sure, but he's not much of an X-Men mainstay and it's way, way too early to start crossing over characters from that mess of a universe.
- Vision facing Vision in an intellectual debate. As others have said, White Vision will probably spend some time self-reflecting. In time, he may come back to Wanda and try and restart their relationship from scratch. That's very comics - Vision struggling with internal strife, but eventually coming to a new understanding and acceptance of himself.
- Wanda finally being A) the Scarlet Witch, and B) finally having a kickass outfit.
- that there are people out there who have Wanda or Vision as their favorite characters in the MCU. They were shortchange so badly for 6 years, and it's nice for them to finally get attention
I hated:
- Hayward. Hate is probably a strong word but I think he might be the weakest character in all the Marvel Studios MCU. A weak link in the acting department too. He's as generic a government badguy as you can find. Also he fired a full clip at some kids.
It's funny... you can skip WV and later see a white Vision and say "they must have rebuilt him," and Wanda and say "cool new outfit, I guess she has a codename now" and be totally fine. Just like you were totally fine if you saw Wasp in the Endgame battle if you skipped Ant-Man & the Wasp, or seeing Spider-Man in Infinity War if you'd skipped Homecoming, or Captain Marvel if you'd skipped Captain Marvel.
Outside of Civil War and the 4 Avengers movies, I don't think any of these movies are absolutely required. And that's one reason they make so much money - 23 movies and a TV show in, and they're still very accessible.
