Well, there was the show The Falcon and the Winter Soldier.
I didn't watch it but most reviews I have seen said it was mid to just OK.
A lot of people didn't watch it, and even then, it didn't do a good job of transitioning Sam to that role.
Using TV as a means of introducing characters is trash, using TV as a means of developing character is even worse

Mackie is perfect as Sam now Cheadle as Rhodey is bad casting. No disrespect to Cheadle he’s a great actor.
