I guess I felt the ending was a little -pffft-. Like the idea of having a crazed Wanda be the big bad was an interesting choice, but I guess not completely nonsensical considering she'd just kinda lost her mind in Wandavision - and I agree the whole thing kind of deflated the whole ending of that show - but skipping out on the White Vision altogether for the culmination of this felt a bit like a missed opportunity (though I am sure he will return.. maybe.. anyway not the biggest deal). The REAL disappointment, I guess, was just having her come into contact with other-dimensional Wanda and then she just folds like a paper airplane. She's crazed/clearly deranged the whole of the rest of the movie and then suddenly comes to her senses when she sees her (other-dimension) kids are scared of her, and then snaps out of it "oh I am bad.... well, guess I will just stop and kill myself." They should have culminated with a huge throwdown Good Wanda VS Evil Wanda fight, that would have been much more spectacular. Ah well.
