In some ways, shows like The Falcon and the Winter Soldier are amazing because they bring the action and intensity of a long Marvel movie.
At the same time, Marvel’s major theaters are saved for big-budget feature adventures for a reason.
In other ways, they could undermine the features planned for lesser-known Marvel characters being introduced in Phase 4 like Shang-Chi, and maybe make their theatrical debut feel less than in comparison.
Sure, I highly doubt any amount of screen time for any hero with a planned series will overshadow fan interest in Spider-Man, but can the same be said for Black Widow?
