Been a life long Star Wars fan but have never really gotten into any of the animated stuff. Is the Clone Wars series worth watching? There are just a lot of seasons, and after watching a few episodes I'm not sure it's worth the time commitment right now.
I just recently did first watch throughs of both Clone Wars and Rebels.
Simply as a star wars fan i'd say yes, both Clone Wars and Rebels are highly worth watching. Clone wars does a lot to flesh out the prequel era (especially getting good a few seasons in, it takes a bit to get good, which is why it took me a few attempts before I finally got through it), and Rebels the era between the prequels and sequels, as well as having a pretty solid story and characters on its own. I' m a couple episodes behind on Ahsoka, but it also has a big impact on these series, given as others have said, Ahsoka is essentially Rebels S5 and Clone Wars has a ton of backstory for Ahsoka's character, both in her past as a jedi as well as her relationship with Anakin which weighs on her.
At very least before Ahsoka i'd watch an 'essentials' list of ahsoka episodes in clone wars, and all of rebels.
