Acting has a lot to do with those attributes. Imagine Gilbert Gottfried playing the role and tell me you’d still describe the character that way.
All, literally all those things you mentioned are the script.
Like seriously, people have serious problem diatinguishing reality from fiction. It is made up! A show build to have simplified almost caricature like characters and plot, so that you can project own fantasies on it.
Gottfried doesn't have the range to express those, of course. You undersell Stewart's work if you express it in terms of what some others can't do - that makes him sound interchangeable with those who can express the scripted character.
