Marvel should have never tried to make Falcon the new Captain America (even if they got inspired by the comics)
People felt a strong connection and personal emotion to Chris Evan's Captain America, and people, myself included, simply cannot connect with a new captain America. I could also see it in my son's eyes and reactions. He would light up growing up to the original Captain America, something which meant nothing to him in this version and was board out of his mind...
Marvel had built something beautiful the should have ended with Avengers End Game.
We loved Falcon more as Falcon, we simply cannot connect with him as Captain America...
The magic is no longer there...
