The Clone Wars CG show did such a good job of selling Anakin's descent and building out his relationships with Obi-Wan, Padme, amd Palpatine. Good thing too, because the movies sure didn't.
Unfortunately the first few seasons are very much a children's show instead of a just a show that's family friendly. And the entire thing is out of order, so you need to follow a watch order guide for all but the last season or two.
