It's an origin story though. All origin stories are going to end with the good guy winning.
I do think Disney has hit a Phase Four slump a bit. Not to say things are bad, but things aren't as consistently good as they used to be. Although when you go from 3-4 projects a year to 7-8, the quality is almost bound to take a hit, unfortunately and the repetitiveness of some of these storylines is going to become more evident.
They are creating so many different "pocket universes" within the MCU though that it's getting hard to keep up, though. It's getting convoluted. This is how I see it -
Gods/Celestial - Thor, Eternals, Moon Knight, Star-Lord (half-celestial),
Street Level - Hawkeye, Kate Bishop, Daredevil, Echo, Kingpin, Jessica Jones, Spider-Man, Captain America, Iron Patriot, etc.
Cosmic - Ms. Marvel, Captain Marvel, Monica Rambeau, Blue Marvel, Kingo, Ikaris, Sersi, etc.
Mystic - Doctor Strange, Scarlett Witch, Wong, America Chavez, Mordo, Shang-Chi, Ned(?), etc.
Dark - Blade, Werewolf By Night, Black Knight, etc.
Thunderbolts/Dark Avengers(?) - US Agent, Yelena Belova, Red Hulk, Thunderbolt Ross, Punisher(?), Deadpool(?)
Mutate/Mutant - Hulk, She-Hulk, X-Men (eventually), Scarlett Witch, etc.
There's just a lot going on right now
