I would ask Kevin Feige to go back to the previous model they had prior to the launch of Disney+ where primary focus is on laying out a narrative / story / saga for the next couple of years, and most projects are primarily theatrical films. Series should be made only for stories that need to be told to bridge the gaps between films (if necessary) and other one off interesting ideas that don't conflict with the ongoing narrative. The goal should be to not dilute the brand of Marvel.
