I'll give my quick reviews cause I'm bored at work.
Wandavision - my favorite of the Marvel shows. Genuinely new and different. Outstanding performances from Elizabeth Olsen and Paul Bettany. Really expands the Scarlet Witch character. Show can drag a little but it's not a big deal.
Falcon and the Winter Soldier - The most straightforward of the shows. Great chemistry between the leads and satisfying return for Zemo. Villains were uninteresting and wasted. Best parts of the show were when Bucky and Sam were just buddying around talking about life. Action was also pretty good. Ultimately it grew the two characters and I'm glad Sam is Cap now.
Loki - Honestly my least favorite show. It was different but it felt really dragged out. Once it became faster and explored the fun in the character, it became better. Tom Hiddleston again crushes the role. Definitely super important to the MCU's future but just didn't quite get it right. Still enjoyable enough.
Black Widow - I actually liked this better than most people. I thought the family dynamic between Natasha and her family was really effective and even heartbreaking at parts. Wonderful performances from the four main cast members. Taskmaster was probably the worst villain or one of the worst in MCU history. Basically the same as FATWS where the movie was better when the characters were just talking to each other rather than the main story.
Shang Chi - Yeah I fuckin loved this movie. Nothing else to say lol. Amazing cast, action scenes, humor, finally a good villain, great story. Really no weak spots.
