I watched the first episode of Agents of Shield when it aired on tv and thought it was terrible and never even attempted to watch another episode.
It started really bad, but it was just spinning its wheels until Winter Soldier hit. After that it gets a lot better, it's never
holy shit fucking amazing but it has it's great moments and I found it overall very enjoyable.
I do remember this guy I know trying to explain to me something about that show before Infinity War or Endgame came out and he insisted I was wrong when I told him nothing from that show was going to matter in the movie. I do feel bad for fans of that show for sitting through however many hours of it there is only for it to mean absolutely nothing in the grand scheme of things MCU wise. that sucks ass.
Yeah, like I said, I enjoyed it thoroughly, but for what it was. There was the hope it would get a payoff in the movies eventually, nothing big like the characters showing up in Endgame or something (I'm sure some delusionals expected it tho), but one thing that I thought they could have done is have a particular character from the show (the one played by Ming Na Wen, the lady who was Chun Li in the SF2 movie) appear in Captain Marvel, since in the show's story, she should have been around Coulson in the 90's. But they didn't, at that point it was clear they were never gonna do anything (although they did put Jarvis from the Agent Carter show in Endgame...).
The point is, like the Netflix shows or whatever else, you gotta enjoy it for itself, not just as another thing in the brand for which you watching experience has to be validated by getting a nod in a movie.
And boy do they need the validation. Got, for instance, to the AOS subreddit, they're still holding onto it. Even when every mention of Coulson ignores his show resurrection, even when the Darkhold is now in play and is nothing like the one in the show, even when the rumors of Daisy Johnson showing up in Secret Invasion turned out to be arse, no, they still say IT'S CANON GOD DAMMIT.
It's not.
Not even Daredevil is canon. They may have brought back the actors, and kept the backstories vague or completely unaddressed, but they already made Kingpin's characterization in Hawkeye instantly incompatible with his Netflix DD self. The terminally lonely man who hid from the world and whose only friend was his assistant, turns out he also ran a wacky gang of russian mobsters, and had a friend in the gang so close to him, he would publicly go out with the friend's daughter for ice cream.
Fuck off, Marvel.
