This project sounds awesome! I binged through all of TCW for the first time not long after Season 7 came out, and I’ve been tentatively thinking about re-watching it; this sounds like the perfect alternative.
I particularly like the sound of what you’re doing with the villains - making Maul a more constant threat will definitely raise the series as a whole and augment its conclusion, and Grievous could definitely do with being more threatening - and I also like your approach of giving each season a greater episode-to-episode continuity, something the original series, in retrospect, sorely lacks at times. Can’t wait to see how it turns out. Good luck!
