TBH I find the word “filler” to be a really strange concept that gets thrown around way too much these days. Now I’m not trying to sound snarky or condescending or anything like that, but how can anything with a character driven plot and/or thematic relevance be “filler”? I can’t really think of anything in this series so far that have actually qualified as filler as I understand the word. Sure some episodes haven’t really moved the story of the Batch forward in any major way, but that doesn’t necessarily make it filler. By the standards that are attributed to the word nowadays we could say that virtually every episode of most old TV shows would qualify as filler as everything usually returned to the status quo by the end of most episodes. Or maybe I’m just too used to old stuff and it’s warping my understanding of modern media?
