You nailed it.
I think they are neither emotionally stunted, nor are they weird, as all the main Jedi show emotions and are never treated as bad for showing emotions. What does it matter when it existed? I think Padme is the main character of TPM, but why should she be the main character of the PT, when the plot about the fall of the Jedi has about nothing to do with her?
What’s terrible about Anakin being a child? And aging down? Anakin was never established in any movie before TPM to have been any age, so how is he aged down? You gave no reasons I think for what’s terrible about any of this, just resorted to claims about Lucas’ ideas of himself it seems to me.
And you didn’t give any reasoning for what’s stunted or more emotionally sensible about any of this.
Did you not percieve the idea of people indulging in their own selfish wants and fears and how that can lead to self destruction and the harm of those you care about and fascism? How is the PT, I think, saying that not something interesting about our own world and lives?
