Short version: The Clone Wars is visually interesting, but in the end pointless - and worse: annoying.
Screen Rant reviews The Clone Wars
Holy cow there's a lot of... angst? anger? annoyance? surrounding the latest addition to the Star Wars saga: The Clone Wars. Me, I'm indifferent. I'm not a huge Star Wars fan (although I was when the first three movies were released for the first time) and I think that George Lucas has run the franchise into the ground and it's all about:
1. Visual Effects
3. Money (see #2)
The Clone Wars takes place between Star Wars episodes 2 & 3, covering the most intense part of the fabled "Clone Wars" first mentioned by Obi-Wan Kenobi way back in 1977 in the original Star Wars film. Therefore we have Anakin Skywalker (destined to become Darth Vader) still playing the hero and a young Obi-Wan Kenobi no longer teaching Anakin but fighting side by side with him.
I really won't get into the story too much. It basically consists of a whole lot of battle sequences, one after the other - all very loud and very "busy" as far as what's going on. The main plot involves Anakin having to rescue the infant son of Jabba the Hut. Yes, you heard right. Jabba the Hut is a loving daddy.
Of course we have Count Dooku in the mix, playing one side against the other and misleading Jabba the Hut into thinking that the Jedi have kidnapped his son when in fact he is the one behind it.
Let's just cut to the chase, shall we?
The animation, once you get used to the style of the characters, is excellent. There is nothing 2D about this, with sequences filmed in a very cinematic manner in regards to camera angles and movement. Hayden Christensen did NOT return to supply the voice of Anakin, and that my friends, is a blessing. Samuel L. Jackson and Christopher Lee returned to supply the voices of their characters, and having Lee voice Dooku is a good thing.

This may sound odd, but with the direction that George Lucas has taken the series, it actually worked better as a 100% CGI animated film. As it was with Episodes I, II & II, they were 90% CGI anyway. The live actors actually looked out of place in those films. At least here everything "matches."
Finally, it's actually an improvement over the three prequel films.
