I just finished WandaVision, and have to admit that all of my reservations about it were completely unfounded.
I did find it interesting to watch after having already seen 3 of the stories that follow it chronologically, which is going to make heading directly into a rewatch of one of said stories - Spider-Man: Far From Home - kind of fun, especially since I now have the benefit of already knowing that Fury is in space thanks to the WandaVision Episode 9 mid-credits Stinger.
And who knows, maybe having the benefit of said knowledge will help improve my opinion of FFH and make the double-bluff appearance of 'Fury' work better.
There is one other thing on my mind coming out of WandaVision, though, which is that I don't get the thinking behind creating Agatha All Along, as I didn't find Agatha Harkness compelling enough to warrant being given her own starring vehicle. Maybe I'll change my mind once I actually get around to eventually watching that show (which I plan to do once we know a premiere date for VisionQuest), but for now, this is how I feel.
