I was looking through people's opinions on Star Wars books/comic books on Reddit. For comic books someone suggested the Darth Vader comics. I read through the first few chapters and it's just him being an idiot and manipulated by Palpatine, slaughtering his own troops and then committing atrocities on non-combatants. Does it get any better? He is gonna remain the bad guy until the end so I am not sure what the value is in reading this. Sounds like it's made for Star Wars wehraboos.

For books some people suggested the trilogy about Thrawn. I know nothing about him except he is a villain too so I am not optimistic about that either. Haven't started reading it yet.
