Well there were a few issues I had with Clone Wars that lead to why I stopped watching it:
1. Like I said watching TV shows on TV just does not work for me. I hate the commercial interruptions. I hate the constant breaks between episodes. It is going to be interesting to see how I do it this Fall as I want to watch Flash, Arrow, and Constantine as they air. I mean, I did it with Game of Thrones this past year, but at least those don't have commercials interrupting the episode every 4 minutes. Plus, I enjoyed watching the first two seasons of Arrow in the span of a few days.
2. I really did not care for the CGI in CW. I thought it looked bland. Sure, the execution looks better than the CGI in older shows like Beast Wars, but I don't feel they are as detailed.
3. Ashoka. I really really REALlY hate Ashoka. She was on Jar Jar levels of annoying.
4. There never seemed to really be any truly credible threat. Every episode I saw had Anakin and Ashoka saving the day, which made it seem like this was not really a war because the Sith were always losing. It also did not help that Grievous did not even seem to be as strong as he was in the Genndy toon.
5. The episodes seemed to be more about the Jedi than the Clones. When I see Clone Wars plastered on the screen, I expect to see a series that heavily features the clones and gives us main characters that are clones with heavily development. My favorite episode of the ones i watched was one that was like 95% on the clones. It was the one where there was some type of creature on the loose and the clones were on their own to stop it.
6. It seemed to contradict the events in the movies as Anakin was not supposed to meet Grievous until after he had kidnapped Palpatine. Yet, he faces Grievous in like the third episode (the Malevolence one I believe).
Now in Rebels, the Inquisitor really interests me a lot as they said they are going to make him a true threat to the heroes, which is good. I'm just curious if we will see Vader appear in the series at all. I also want to know where the timeline takes place as I actually would love to see a story set after the first Death Star has been blown up. I mean, there has to be more to it than Vader just calling Palpatine to tell him the Death Star was blown up and he starts crying over the phone.
