I honestly prefer either the chronological order or the machete order. I just can’t bring myself to watch the Original Trilogy first and then the Prequels. For me, you’ve always got to end with Return of the Jedi, because that ending is the most satisfying. If you finish on Revenge of the Sith, the Saga ends on a really depressing note. But if you end with Return of the Jedi, you close things out on a happy, uplifting note. That’s why I stick with chronological or machete order: both let you watch Revenge of the Sith before Return of the Jedi instead of after, and that just feels like it makes way more sense.
