It’s a half-hour non-serialized kids show driven by mostly action (basically never character) so I guess that’s to be expected.
I find complaints like these are usually made by people that either never watched the series or never made it passed the first season.
The first couple of seasons, especially the first, are all over the place in terms of when they take place in the timeline. But beginning around season three they really started to focus on keeping the series on a linear path through the war.
Also, the series is packed with character development. And it’s not just focused on the main characters.
We see a batch of clones from their first assignment through to the last days of the war.
Ahsoka throughout the entire series continued to grow and mature as the series went.
Even the villains were never stagnant but continued to grow and evolve as time passed. From Ventress to Maul and Savage, they all got their own story arcs devoted to them. Even a character like Hondo saw some growth throughout the series.
So I find claims that the series was non-serialized and lacked character growth to be outright laughable.
I have seen every single episode (and recently - all last year). Just because there was character growth and development doesn’t make the show character driven. Just because there were arcs doesn’t make the show non-serialized.
I’m not saying the show was completely lacking in character progression but it’s hard to care about them in the same way that you do about the Rebels group even (a core set of characters in every episode and much more serialized).
Don’t know what it says but pretty much all my favorite episodes are the clone-centric ones. They always nailed that.
