For instance who was the missing person/witness? Where did the actual Vision go? How was there a fucking witch cave underneath the house and how did Vision (if it was Vision) a lot there?
I also disliked that in the end Wanda just simply accepts that her children vanishes. Felt like the whole story line with the kids was pointless. Aswell as with the fake Pietro.
In the end they just went the lazy route. Agatha was the big bad, have a fight scene and end the series. Thats it.
