That’s just a reboot because those are books that have been adapted and updated multiple times over the years, sometimes with zombies.
A better comparison would be the original Star Wars trilogy and the new movies set around that time. They’ve recast some actors, the props and costumes are far more detailed.
For example, the classic stormtrooper.
Those are just different versions seen in the original trilogy, a lot of variation because they were based on molds.
This is a close up of the details on the new one from Rogue One that takes place right before A New Hope. The painted details on the old are practical and serve a function now.
They made a better costume because the technology had improved. All of these helmet are the same in-universe piece, but look different visually. They didn’t downgrade the suits a few hours after Rogue One.
