Personally, I really hope they stop trying to tie this series in too closely with Clone Wars and Rebels. (And please understand I absolutely adore one of those series and abhor the other.)
My take is that The Mandalorian is kinda “the second chance” to pull in both old fans AND new to Star Wars after the disappointing reaction to the Disney sequel trilogy. And if too much of the new show requires knowledge of two somewhat lengthy animated series, that program is likely to end up alienating much of its audience. I’d suggest sticking to the OT and PT, with subtle “Easter eggs” for the hardcore crowd.
My brother and I were discussing The Mandalorian this afternoon, and he commented that he was starting to feel lost due to the inclusion of Bo Katan and Ahsoka as he never viewed the animated efforts. At first, it seemed to him “Hey, cool new characters.” Until he went online to find he wasn’t a True Fan and was clearly not knowledgeable enough to really enjoy the show... Sigh.
Any Jedi that appear in the future I would hope are original characters (or we get a special appearance from Mark Hamill).
Anyway, my two bits.
Also? Personally, I’ve loved the series thus far, and this season has been a ton of fun. Just, again, really hope The Mandalorian ends up being its own story and not just a spin-off of CW and Rebels.
