I agree with you except for Strange being forgettable. I think he’s one of the more interesting characters.I just think there needs to be better justification for taking down one of the greatest rides ever made based on one of the most iconic pieces of media ever made than "But Disney doesn't own that." Especially if the replacement is something as forgettable as the MCU version of Doctor Strange.
For instance the MCU version of Strange is far more interesting than MCU Hulk, who is far more iconic.
