Well first off, I don’t care about anything outside of the movies, but that’s a personal choice. With that said, what exactly are you using as your personal canon (I hate the term “headcanon” and refuse to use it)? Is this based on something tangible, or just a fan fiction story in your head? Did someone create a good Anakin character?
Really, just TCW and the RotS novelization did wonders for me. I think that the book format is much better for telling Anakin’s story, and TCW made him a much more likable character. It also made his transition into Vader more believable by sprinkling moments of darkness throughout. Moments like these make some of the sillier stuff worth it;

Context: Obi-Wan faked his death and disguised himself as the dude who “killed” him, Anakin was under the impression that Obi-Wan really was dead.
