The micro-series is too rushed, I don't like the over-the-top action, and it relies too much on the viewer having read the comics and whatnot to understand what became of Ventress, how Anakin got his scar, etc.

The newer series has a better pace, better characterization, and better storylines. Unfortunately, there's also a lot of prequel-style universe-shrinkage which bogs it down a little too much, and I just don't like how the animators have made Rodian eyes look all sparkly blue-and-green.

Both series have lame villains (except for Cad Bane, who's awesome).
