The clone wars/siege of Mandalore flashbacks were outstanding in live action.
Rex!
The Vader breaths/Anakin's eye color changes/the color of his lightsaber during the last part of the duel, wow.
Anakin in general, so good to see him back.
The lightstaber duels themselves, loved the choreography.
Young Ahsoka.
'I won't fight you.'
Jacen hearing the lightsabers.
The Purrgils! Such amazing visuals, the faces/smiles of the New Republic personnel/X-Wing pilots as they flew by were me 100%.
'I respectfully disagree.'
That final 'may the Force be with you.'
The music in the episode, man it was perfect...
