First of all, welcome to The Clone Wars’ fandom. I certainly agree that the nuanced portrayal of the clones in this series is among its strongest traits. Personally, I consider the four primary story arcs of TCW to be the stories of Mandalore, Dathomir/Maul, Ahsoka, and the clones – which is why I am so happy that the four-part series finale featured each of these threads.
One more thing - I can see that you’ve just joined the boards, and I want to let you know that double-posting as you’ve done here is against the rules, which can be viewed here: Rule Index: All Rules Here. Don’t fret - this is a mistake made by many new folks.
