@AllFor4 That’s not how I interpreted that line at all. Happy says “Tony wouldn’t have done what he did if he didn’t know you would be here after he was gone”. He doesn’t mean he sacrificed himself FOR Peter, he means that he knew he’d be leaving the world in capable hands. The whole point of the movie and that scene is Peter learning to step out of Tony’s shadow and be his own hero. Happy’s trying to help him realize he’s capable. Literally right before that line he says “You’re not the next Iron Man. Tony couldn’t even live up to Tony.” Telling him Tony died for him would literally just make him feel worse and wouldn’t make any sense as a response.
I’ve never understand all the “Iron Boy Jr.” complaints. The whole point of FFH is Peter learning he’s not the next Iron Man, he’s Spider-Man. Which is why it ends with him embracing his Spider-Sense and finally doing the iconic swinging through Manhattan. Curious/skeptical where NWH brings him, but I’ve never had any issue with the Peter-Tony dynamic.
So aside from poorly timed jokes:
Iron Man - Coulson saying that they decided to try out the name "S.H.I.E.L.D.". Yes, it was retconned later, but just the fact that an intelligence agency would not have immediately realized their organization's name had that acronym is just studio pandering.
Thor - Dutch Angles but also the shouting moments from Hemsworth, Hiddleston, and Hopkins just feel so cringy to me.
The Avengers - "I have a plan. Attack."
Iron Man 3 - Killian not dying when the Mark 42 was blown up. Made perfect thematic sense, and the unnecessary Super-Pepper scene just took me right out of it.
Avengers: Age of Ultron - "I think you're being hard on yourself." "Here I was thinking that was your job." is the rock bottom of this plotline.
Black Panther - "WHAT ARE THOOOOOOOOSE??"
Avengers: Infinity War / Endgame - The 1 in 4,000,605 thing really annoyed me. Like all that made me do is look for plot holes.
Ant-Man and the Wasp - The part where Janet says if they fail, it will be a century before they can find her again. Just like Infinity War, these stakes are unnecessary.
Spider-Man: Far From Home - The part where Peter calls a drone on Brad just felt silly.
WandaVision - The Bohner scene added absolutely nothing to the series, and this is from someone who didn't want him to be the Fox Quicksilver.
The Falcon and the Winter Soldier - The only part about Walker's arc that bugged me was the joking with Bucky. I can buy you still working with them for a greater purpose, but these guys do not like each other at all. The Zemo mask was pure fan service too.
Loki - Not a fan of the acting/dialogue during the Alioth scene.
Black Widow - Why did we need the pheromone lock? What did that change?
Shang-Chi and the Legend of the Ten Rings - Trevor understanding Morris fluently was just a bit too unbelievable for me.
Eternals - The sex scene felt completely shoehorned in.
We saw Mantis struggle to sedate Thanos, and she was able to put a Celestial to sleep. Thanos probably would've been able to resist Kilgrave.
Maybe after Feige retires, but for now, it’d look a bit pompous.
Loki is set in a timeline directly branching off of the main MCU timeline, showing the continuation of a character already introduced. The Raimi and Webb series takes place in different universes within the multiverse. So the situations aren't exactly the same.
To expand, the Raimi trilogy (Earth-96283) and Webb duology (Earth-120703) are just as connected to the MCU (Earth-19999) as the main comics timeline (Earth-616). Or the X-Men films (Earth-10005) for that matter. They're all just different universes within the Marvel Multiverse. In No Way Home, Doctor Strange is just opening a portal between the universes (I'm assuming).
So if you want to add the other Spider-Man to the viewing order, you could, but it's certainly not essential, and you could theoretically just keeping adding anything with a Marvel logo to your viewing order at that point. Easier to just keep it simple.
And I agree that anything essential to No Way Home will be directly addressed within that film.
