What did Captain Marvel do in the MCU before Endgame? (spoilers maybe)

[DeTess]

Oh hey that's a good point. Can they show that? Can they show that in the films? Can they establish any of this stuff? Can the people who make these films at least look as though they care about making a good product that can't just be summed up with the phrase "Good guy strong and make punches and shot lasers and go zoom-zoom!"?

Hey, I completely agree. The lord of the rings trilogy is also garbage because they never showed why Aragorn didn't take over Gondor before Sauron's return so he could have the armies in place and ready to contain the dark lord. And House is an absolutely garbage medical show because House never figures out the universal cure for cancer despite being shown as really smart. And the Doctor could have just traveled all the way back in time to prevent all the things from ever being a problem...

Seriously, though what are you trying to achieve here? If you demand that everything relevant ever are always shown on screen, then every movie ever is full of plot holes. Yes, even that one you really like and think is perfect. Maybe you should just take a breather and let go of this hate you've got for MCU? There's probably lots of media out there that you do enjoy, and you'll be happier that way.
