You're arguing against specific aspects of my criticism without addressing the entire criticism. It's not the what, but the how. The Illuminati scene, even by your admittance, served two major purposes. 1) Show how powerful Wanda was, and 2) Get audience applause. Since showing how powerful Wanda was had NO impact on the story what so ever, then it only served one purpose, getting applause, and I think that's cheap and cynical. Yes, sometimes they show people using one power and then never again or only when it's convenient, but usually those scenes serve a purpose other than showing the power. This didn't. It show that Wanda could turn zombie strange, or Wong, or America, or whomever, into ANYTHING via reality warping. She could turn zombie Strange into a dog, or simply dust, but chose instead to throw witch lightning at him the entire time. So showing that she HAD the power to turn him into a dog or whatever serves no purpose at all. It didn't make her a bigger threat or give Strange anything to overcome. As I said, if you completely remove the Illuminati scene, it changes the story 0%. That's not a good thing. I think it COULD have been cool, but it just wasn't. It was applause and nothing more. If you're going to bring back Stewart and Mount and introduce a new Captain Britain and Reed Richards, then make them have significance. They just didn't, sadly. If you loved it, cool. A ton of people did. I don't want to take that way, but it's still a pretty poorly written scene. Don't get me wrong, I like bad stuff too now and then. Doesn't make it great simply because I had fun. I'd have a good time an airport Sbarro. But I won't call it well made pizza, you know? Spider-Man No Way Home had a lot of flaws as well, but because I was so invested in the story, the characters, etc., then I was able to largely not be bothered. But because I was not terribly invested in the story/characters in this movie (at least not nearly as much), then the flaws stop being so forgivable. A well constructed plot, character arcs, emotional buy in, etc., would have gone a long way for me.
@Kattle, I agree about Reed. He's a good fighter, but not against someone like Wanda. I'd imagine he was there to talk her down, somehow? But....yea, being the dude right in front of her isn't in character for him. He'd be in a lab or something trying to devise a way to take her down, not standing in front of her telling her how to defeat their secret weapon. It's a situation of a writer writing a character MUCH smarter than the writer is. It doesn't usually work out.
