I think I would describe the Falcon and the Winter Soldier as endearingly bad. It wears it's heart and it's message on it's sleeve...and it's a good message, but the lack of subtlety is to the detriment of the story, and some of it's characters.
I appreciate a grey character as much as anybody...not every story needs a clear villain and hero...but by the last episode of this show, I know how I feel about Falcon/Captain America, but I feel very little about the fates of Karli, John Walker, and the Sharon Carter reveal was kind of a shoulder shrug.
Sebastian Stan and Daniel Bruhl are great in their roles, but both end up being relatively minor. (Sebastian Stan, surprisingly so)
Aside from characterizations, the show is littered with compelling action sequences, and occasional powerful dramatic moments...but the editing ranges from abrupt to incoherent. I heard the show described as one movie broken up into six episodes. It feels more like a 10 episode season with 4 episodes having been removed at random.
In the end, there is enough goodwill generated by the MCU as a whole, and some of the actors specifically to pull me through, but I doubt I'll be watching any of this again.
