In fact, due to the storyline being non-linear, they don’t consider any of the episodes as “filler.” And while there are a lot of episodes to watch for the newcomers to this show, it’s definitely worth watching in order. And whether this series has fillers or not is up to you to decide after you’ve seen them all.
