Star Wars: The Clones Wars fills a very important role; the show gives you all of the context before Star Wars Epiodes I, II, and III. This bridge is so important that I recommend that everyone watch this show first before the movies I mentioned.
Ahsoka Tano is also an amazing addition to the Star Wars cast and I love her very much, her character development was handled with such beauty and grace. As a woman, she is one of the best female characters in the Star Wars franchise.
They also improved Anakin Skywalker's character from the live-action movies, giving him more depth and as a result, he becomes much more likable. Obi-Wan is a sassy icon and he's always a delight to see on the screen. All of the antagonists were amazing. The writing and direction of this animated show is mind-blowingly wonderful!
Despite the filler episodes, the overall story is a 5/5. Please watch Star Wars: The Clone Wars if you haven't already.
People have always created lists of episodes to skip if you don't want to watch the filler episodes, if you love Star Wars you cannot miss out on this show.
