Maybe it’s confirmation bias on my part, and obviously the following is very subjective… but in my opinion there is a significant difference between a adapted series the showrunners care (and like) the material, and where they are just using it as a vehicle.
It’s part of the reason you adapt a book, comic etc in the first place. You inherit its fan base. There are folks who’ll watch it because of what it is, and they want it to succeed; they have favorite characters, arcs, badass moments, whatever they’d love to see depicted. It can elevate the series’ quality even further than it has a right to, just because of that synergy.
For example Ahsoka is not perfect, but damn if you can’t tell the folks who made it liked the cast of characters and their history. They keep making references to their past. It’s written to evolve and progress their storylines, and they’ve definitely made changes compared to Rebels, but those are expected both because it’s set in the future and the different cadence of a live-action work versus an animated series.
Then (and apologies to anyone who likes those, this is just my personal opinion!) I watched Wheel of Time or The Witcher… man. I can’t say the same thing. I don’t know the showrunners liked the original material much at all. They’re using it to tell some other kind of story kind of similar but with different beats, different directions, just… something else.
If they had the talent to write something of their own, and I’m sure they do, just do that, dammit. If it’s good enough then maybe I’ll be a fan of your original new work too.
Anyway. Ahsoka. It’s fun!
