Wholeheartedly agree that Tartakovsky’s Clone Wars is the perfect 2.5, it fits with the movies better than Lucas and Filoni’s TCW, too, imo - though I recognize and respect what TCW does in terms of just playing with those characters and putting them in stories that maybe shares something interesting about them, with not that much care for an absolutely linear story to go along neatly with the movies.
But yeah, short answer, Tartakovsky micro-series.
