Once again, I was quite pleased at how well the new episode held together without requiring knowledge of either animated series. They're doing a great job of introducing the characters for those of us who've only ever seen the movies, but including things that provide some extra payoff for people familiar with the animated stuff and/or the books. Nicely done.
On another board I visit, I'm seeing shit like "So who is this Ashoka (sic) and why's she so important?" Answer: She's the one Bo-Katan said to find. Not that hard to follow. If she has greater importance than that, it's not explored here, and I never felt like I was "missing" anything by not knowing her backstory. She's obviously a badass in her own right, and strong with The Force. For the purpose of this story, that's all we needed to know. I happened to know some of her backstory from discussions here, so her remarks about emotional attachments had a little more weight, but everything she said and did worked fine for me.
Same with Bo-Katan and the other Mandalorians we met a few episodes back. I saw three Mandalorians obviously from some other sect. When she pulled off her helmet, I thought "Whoa, this group obviously doesn't have the helmet rule" while others went "Holy shit, it's Bo-Katan!" Then she introduced herself and the others and we were all on the same page. Cool.
I think people just like to complain. They're not "missing" anything; they're just whining that they don't get the extra reward that others do for knowing the other material. Sorry, that can't be helped. I think Filoni, Favreau and company are doing a hell of a job keeping a delicate balance.
