Actually I disagree with you slightly on that. I think the problem with the prequel films was the tendency to try to show Anakin too much in a sympathetic light. I think that factored in first introducing us to Anakin as a kid, which I thought was a huge waste of time, and then developing his relationship with Padme in the second film, and then there seemed to be a rush to get to Vader in the third film. Anakin was heroic in TPM, perhaps not so much in AOTC, and then again in ROTS, and even if they didn't spend a lot of time showing his heroics on film they talked about it or how strong in the force and potentially great he was.
I do agree that the Clone War series does provide an opportunity to flesh out Anakin's character and to show different sides of his personality which is a good thing.
