Really interested in this. I’ve only watched the show the once, and don’t have the capacity to load it in and thoroughly analyse it right now, but I think you have exactly the right approach.
That said, if you do a watch-along analysis, I’d love to jump in and join you on that.
How certain are you that you want to run with the movie length idea? I found “as long as necessary” serves my Clone Wars edits well, without binding me to a rough runtime, and that coupled with using text crawls up front allows me to pull weaker content out of the episodes themselves (where necessary) and to pace and bridge the content more freely.
I’ve done work with raw Bad Batch files, so if I can help you with any of the technical stuff, I’ll be happy to.
