"Real-life Star Wars tech" confused me, since it's a missile defense system IRL, but it's talking about:
The massive screens and virtual set technology pioneered on more modern shows like The Mandalorian.
“Yes, it grew increasingly difficult and frustrating to go out into the woods of British Columbia and pretend it was another planet”
I quite liked the feel of the series being in woods so much, and it made sense given that many of those "worlds" were pre-industrial (plus alien tech).
