not sure how many episodes I've seen

and in no paticular order , I'd watch a couple episodes here , couple there

but like any show , it sometimes takes till season two or three to really get it's footing

watch enough episodes to get a idea who these characters are before Ahsoka comes out , is probably all you need

or

you can find enough short videos on youtube to accomplish the same thing

Ezra and Sabine and Thrawn , all coming to live action in Ahsoka
