Andor excluded of course, it’s so 70s right down to formally being the grimy thrillers Star Wars '77 would be analyzed as cultural antidote to. The writing is timeless, the mullets and moustaches, even the Niamos beachwear feel so in line with ANH’s time period. And don’t forget the junky analog tech! Machines are big and unwieldy; Dedra has to do what’s basically an archive search by asking an attendant to collect those files from giant tube computers. There are illegible glass interfaces of lines ala Yavin and Hoth, tons of tactile knobs and switches and buttons, etc. Modified AK-47s as the symbolic weapon of revolution circa the 70s is loaded imagery, just like the modified StGs and Mausers in the OT evoke WWII. I was hyped as hell when Cassian was sentenced to prison by a 70s credit card machine.
And it makes it thematic. Nemik has a whole right-to-repair bit about technology being lost or forgotten; one of the many ways Empire imposes its will is through centralized uniform technology, moving populace away from the different lines of communication and information they maybe once had access to. Seperatist projects like tactical droids with databases in their head, Techno Union touch screens, or Umbaran bubble fighters fall by the wayside in distinctly important ways. It’s great!
Stuff like that really puts us right back into the space A New Hope is in. Whereas, yeah, it feels like a lot of other Star Wars stuff recently just conceptualizes “Star Wars” as anything that’s been in the movies before. Fair game for inclusion at any point, regardless of its faux-historical context. Aside from looking like a very modern Disney+ show in lighting and costuming, I wouldn’t be surprised if there isn’t any real technological difference between High Republic and Mandalorian eras in Acolyte. I would have loved design that feels more historical than just “cool” for the characters.
