Be careful. Comparing novels to a web series and using your
conclusions may not work. Quick, name three successful movies
or TV series adapted from Asimov novels.
I'll throw you another bone, Rik. The Bicentennial Man by Isaac Asimov was plot driven and was a disappointment. But, like I said, 2001 is plot driven, with almost no character development, and it remains iconic.
That said, most sci-fi films are plot driven, which means there will be a big opportunity for character-driven stories.
