The Clone Wars are acceptional, especially seasons 3 and on, when you really start to see how deep Palpatine's fingers are in everything without a lot of screen time by the Supreme Chancellor or his counter ego.
I really wish that some of the elements of the Revenge of the Sith novel had made it into the movies.
First of all, the final seduction of Anakin and the conversation between Palpatine and Anakin was exceptionally well done, and it really explained the seductive nature of the Dark Side of the Forth.
Throughout this book, there's a reference to Anakin feeling like there's a dragon of fear burning in his heart. When he chooses to accept the Dark Side, he can invasion in his mind, unlocking the furnace that is his heart, pulling out the dragon and crushing it with his boot. The Dark Side freed him from everything including his morality that prevented him from taking what he wanted, which was the power to save the ones that he loved.
When he went to Mustafar to slaughter the Seperatists and he had some great Vader like Dialogue.
One leader begging for her life said "Lord Sidious promised us a reward" "And Vader replied with something like "Don't you find me a pretty reward"
And the main leader cried out "Lord Sidious promised us that we would be left in peace", and Vader replied "The communication was bad, he promised you'd be left in pieces".
In the book you could see that Anakin was already plotting to kill Sidious so he could rule the Galaxy and bring peace.
In the Obiwan Anakin duel they had some great dialogue at the start where Anakin, basically asked Obiwan to run, and go and mediate because he didn't need to save the Galaxy anymore, you also got more insight into why Anakin felt that the Jedi from his point of view were evil. For the most part his reasons were fairly self serving but they were reasons.
In the fight between Palpatine and Yoda you got into Yoda's head when he realized why the Jedi had failed and it was heart breaking.
Some of the differences

This part of the book summed up everything Vader
In the novel Dark Lord which is sadly not Canon anymore, in the end, Anakin believed that he was trying to save his wife from death, and Obiwan from ignorance, but they wouldn't accept what he had become. He also believed that his actions had bought peace to the Galaxy and balance to the force.
