Falcon and the Winter Soldier. Giving it a shorter runtime would have cut off a lot of the fat like Sam dealing with getting a loan and helping his sister with their family business or them going on a detour to Madripoor to meet up with the Power Broker.

I get a big part of the series was the racial prejudice Sam would experience but it felt like those issues were completely seperate to his activites as a superhero. A tighter run time would force the writers to weave those themes of race/class into the primary storyline.

Also a bigger budget means the scenes we already got could look more impressive. Walker as the new Captain America is a great angle but he and his partner felt weirdly small scale considering the amount of fanfare that was surrounded with Walker becoming Cap, especially given his lack of powers. Give him a support field team on missions to really cement that this Cap has the limitless support of the government behind him while Sam is largely left to handle things himself. Also give some of that budget to the Flag Smashers so they appear more credible as a proper threat and visually impressive.

For the reverse side make Eternals a miniseries. That film was a mess.
