I'm re watching the movies, clone wars and rebels in anticipation of the new film. I don't think star wars works in book form but I'm interested in some of the comics although I have no idea which ones are any good or important in terms of plot ,are any worth reading? (I've read anakin and obi wan and the darth maul one set after the clone wars series)
Darth Maul (the one before TPM)
Darth Vader (both the 2015 and current one)
Kanan
Doctor Aphra
Lando
Han Solo
Princess Leia
Shattered Empire
None of them are "necessary" but the Vader comics really flesh things out and Shattered Empire ties in with Battlefront II. Kanan is a great companion story to Rebels. The others are just fun.
Poe Dameron is surprisingly unimportant but it seems like it's finally starting to pick up (and akso probably close to ending).
The main Star Wars comic is all over the place in quality but it does tie in with Vader 2015 and Aphra, and ir just switched to a better writer, so it's also worth reading but it's not a top recommendation. It also has a lot of art problems.
edit: For the main Star Wars comic I'd say read the first four arcs (through Rebel Jail), then skip until Screaming Citadel which unfortunately kind of has to be read if you're reading Aphra (or you could skip those Aphra issues as well), then skip stuff again until Gillen's run starts.
