I just finished the show, & I absolutely loved it. I'm a fan of the show & have been since my son & I watched the movie in the theater. That being said, I would not be unhappy if the show was over.
There's no negative feeling behind this, I just feel that with Ahsoka being introduced in the movie, that this is the perfect time & story to move on. Now if the show continues, I'll be thrilled, but I'd like to see more of an anthology feel to the show. That has been pretty well covered by doing the stories that follow the various other characters like the clones, droids, & politicians, but the feeling that the show had 3 main characters in Anakin, Obi-Wan, & Ahsoka has always been the underlying feeling.
As of right now, I can't think of any character on the show that we don't know the end story of, Maul & Ventress aside. Now I get the feeling that I have read the last book in a series, & now I'm going back to read the middle one. I'm not sure if there's any more to do with these characters. There's only so many ways you can show Anakin's feelings of anger, attatchment, & disillusionment, & Obi-Wan's fear of what will happen to Anakin.
But, I think that my biggest problem now, is that the 2 'hero' factions in the show, Jedi & clones, have been made to the point where you almost can't root for them. The clones are great in military stories, but we all know that they're puppets. The Jedi now, well, this one story ALMOST made me think that what happened in Ep III was poetic justice.
