The Clones wars had some great episodes and story arcs along the way (still did not fully see the last season) but it had few things going against it from an "old fan" point of view:
- It's prequel centered.
- It's a show for kids. (IMO a great show for kids)
Anyway, the show improved greatly from the awful first "TV movie released in theater" and it was a nice time watching it.
That said I'm not going to cry on its grave. And if I remember well, they planned to make 5 seasons from the start.
So making more seasons now that Star Wars is about to move along to something else would not be a logical choice.
