So to fully understand this movie you need to know the Clone Wars story? This is confusing. Let's stick to movies that are easy to see, please Disney. I don't have time to go back and watch tv shows!
I don't think you need to have seen anything else, especially not Clone Wars, to like this movie. Yes, there are things that will mean more to you if you have seen the other movies/shows, but I can't think of anything that was important to the plot that required some prior knowledge.
