How would you make Endgame have a more epic feel?

I wish Stan Lee could have played cap at the end, impossible because he died, but also would have been even more meaningful because he died

Because they were acutely aware of the hype surrounding Cap saying the line, so they treated it as a self aware 'hey guys, this is the moment! Heh, see, we finally did it!'

It would've also made his cameos better

Having the three fighting Thanos being much longer, and having heroes fighting Thanos personally being the vocal point of the final battle (with the other carnage being the backdrop) would have been nice.

Meme a minute bathos took away the gravitas lots of times. I sensed the Russo’s borrowing Gunn and Waititi’s playbook. They should have stuck to CW and IW in terms of tone.

As wholesome as that thought is, it would have felt jarring and out of place. The audience knows who Stan Lee is, he's made a cameo in almost every Marvel movie, and made one earlier in this very movie.

This would have been terrible, no offense. Lee can't pull off a scene like that, is clearly not the same person as young Cap, and would only serve to be self aware claptrap. It's the same shit as people saying he should have been the old man that told Loki off. He's fine for cameos but not shit with some gravitas.

Is Stan playing Steve or another Cap? Unless Stan comes to hand Sam the shield and Steve was implied to have stuck behind in time, it doesn’t really make sense.

Gamora kneeing Quill in his infinity stones wasn't needed.

Yeah that's a fair point, he's not really an actor, I just wish they'd done something to commemorate him, I didn't sit through all the credits, but did they do an end card or anything like spiderverse did?
