This show is awesome!
Now let me get this out of the way first, some episodes are worth skipping. For a show to be this good, not all the episodes are great. Most of season 1 isn't that great, and even the last season has an story arch that you can probably skip. The great parts of this show though overshadow the bad parts easily.
This show made the prequels relevant. Not a lot of people enjoy the prequel trilogy (I-III), especially when it first came out. There are characters that are wasted in the prequels that are made way better in the clone wars tv show. Anakin Skywalker is way better in this animated series and it really makes us understand his struggle. Along with him, other characters such as Obi-wan and Padme are made more interesting as well. New characters like Ahsoka, Asajj Ventress, Captain Rex, and many others are welcome additions. There are returning characters as well like Boba Fett.
Maul also returns in this show and his stories in this show are amazing! His confrontations with Obi-wan, Palpatine, and Ahoska are very well done.
This show does have dark themes as well as just a little kid elements to it. This show goes over war, slavery, morals, and many other principles that make this show interesting.
The clone wars also flushes out the clones themselves and we actually get to know some very well and cheer for them.
The animation gets better every season.
It's action packed, has complicated characters, and is very entertaining.
This show is better than most of the movies in my opinion and is just as good as the Mandalorian tv show.
Highly recommend to anyone who enjoys star wars!
