The only two I flat out dislike are What If and Loki. The others I find enjoyable enough but noticeably flawed.
What If - Many characters were flanderized or very out of character (Coulson's admiration for Captain America was exaggerated to the point Coulson became a creepy pervert who sniffed Thor's dead body; Vision's defining traits are his compassion and selflessness, yet the What If writers had him feed T'Challa to zombie-Wanda for cheap romantic angst reminiscent of a CW show.). What If felt like a Robot Chicken parody.
Loki - Zero resolution, and filled with hollow fanservice to distract from the lack of a story. The "plot" went in circles for the last four episodes, then ended on a big cliffhanger. The whole show was just a six hour long teaser for Quantumania. The first two episodes were promising, but after that it really lost focus.
FatWS - Appreciate the willingness to shine a light on dark parts of American history, but had pacing issues and the script could've used more fine tuning. Loved Isaiah. Did not love Sharon's villain turn. And Bucky's rehabilitation was way too rushed (his entire amends list completed off screen? That could've been a whole show on its own. They skipped past Bucky's whole confession to Yori, it should've been like the scene at the end of The Bourne Supremacy.)
Moon Knight - Nice to see some Egyptian culture, but had uneven pacing and underutilized some characters and worldbuilding. Disappointed with how Jake Lockley was depicted as the violent boogeyman personality like you see in so many generic movies about people with DID.
Hawkeye - Fun but tried to cram too much in IMO. I love Yelena, but when she showed up Echo got extremely sidelined. Lucky was adorable, but the only reason he's in the show is because he's in the comic the show takes inspiration from, he doesn't do anything except sit around looking cute. I like Jack, but was disappointed the show removed his mentor relationship with Clint (hopefully he can mentor Kate instead in future appearances).
Ms. Marvel - My second favourite of the MCU/D+ shows so far. I wasn't feeling the early episodes with the high school drama, but I loved the latter episodes in Karachi (I'm not South Asian but those scenes felt very familiar to me). Appreciated the exploration of Partition. And Iman Vellani is a treasure.
Mostly enjoying She-Hulk so far but I'll reserve judgement until its finished.
