The action sequences/lightsaber fights look exciting and I like the supposed premise that she is searching for Ezra.
The introduction of Sabine has the possibility of being an exciting character.
If time travel is part of this series maybe Ahsoka will take omega back to Alderaan at "0 BBY" and leave her there.
Given that Thrawn has obviously survived the clutches of the giant space whales it's almost assured that Ezra has survived also. But why was Thrawn able to escape and return to the present yet a search has to be invoked to find a powerful Jedi Knight?
What I feel/see at least for right now, as negatives don't surprise me.
1. The new dark master looks like he will be nothing more than a poor mans Darth Vader. A sith lord wannabe.
2. Mads Mickelson will have to give his greatest acting performance ever to impress me as Grand Admiral Thrawn.
His style of speech is a bit slurry and just a tich lispy. Thrawn should be speaking clearly, with authority and demanding loyalty. In my opinion Mads always comes off as Mr. Evil while Thrawn is the epitome of strength, clarity, presence and persuasion.
Plus this is a dudsney show. That fact alone gives me no confidence that there will be originality, imagination or creativity.
