I think everyone can agree that Thanos caused a major problem for MCU. Now they have to resort to turning heroes into villains to make it interesting - but in this case the hero turning into villain and the whole shebang already happened in WandaVision. This movie just presses undo button on Wanda's character development and sends her back to the middle of WandaVision. I think anything other than Wanda turning into villain would have made this a better movie - admittedly not a high bar given my rating.

The titular multiverses appear for a few interesting minutes and those are the most interesting few minutes in the movie. I got thoroughly bored and decided never to watch another MCU movie in the theatre. (I have watched all MCU movies since Avengers 2012 to Avengers : Endgame in the theatres)
