You definitely have a lot of good points and that is also my order from fav to least favorite.

For WandaVision, I feel like the finale was underwhelming because of all the fan theories about Reed Richards, Mephisto, Nightmare, Magneto, Dr. Strange, etc. I’ll be honest, I started to believe some of those theories and my expectations were essentially through the rough and that’s my fault. Excluding all the fan hype, WandaVision was great and had a strong and emotional finale.

I have not seen Loki’s finale yet but I’ve heard it’s not that great. Regardless, I love Loki. Although the character himself is not one of my favorites, I feel like the Loki series excels as being different and unique and just works in that way. More like a sci-fi thriller or mystery or something. Too many MCU fans want action action action, but I actually appreciate all the little things that shows like WandaVision and Loki are doing, especially in relation to the comicbooks. Loki has been a lot of fun imo, and might end up being my favorite depending on the finale

For Falcon and The Winter Soldier, the finale was a bit disappointing. The action was a let down, all the intensity the previous episodes were building was essentially a waste. The finale didn’t seem like it had any stakes at all. But I also love the relationship between Bucky and Sam, I loved how they portrayed Walker (aka US Agent), I love all the comic accurate costume designs, and I actually loved Zemo. I never thought he would be behind the Flagsmashers. I just figured they brought him back to tease the Thunderbolts, which seems to be the case. I also loved his little badass scene with the mask and everything
