This man has been Jango Fett, Commander Cody, and countless clones on the big screen. Now, he has the challenging task of playing Boba Fett, one of the most beloved characters that we never really got to see in live-action. He did an excellent reintroduction in Mando, but the training wheels are off, and it’s time to give this man the spotlight he has earned since his first appearance in Attack of the Clones.
You CANNOT bring in Luke Skywalker, Leia, or any character that would cast a shadow over Boba. He's the star, so let him shine.
Also, as far as his character, how about sharing his father's same motives after all these years? "I'm just a simple man trying to make my way through the universe."
