I would watch it in a more peculiar way, but this is the best way in my opinion: 4, 5, 1, 2 ,3, 6, 7. This is called the "flashback sequence". It presents the films in an order that preserves the most important surprises, and shows you how Darth Vader became who he is like a flashback episode. It also mostly preserves the SFX since you start with the oldest first. You could watch them in order from 1-6, but the surprises are ruined and the SFX are very jarring.
From my point of view, the episodes 4 (New Hope), 5 (Empire strikes again) and 6 (Return of the Jedi) were made first because the story was more interresting, but the best way to watch them is definitivly in the chronological order.
😨😥😥😥😲😲😲Man take a yr or season off lol. You will have to have nothing important scheduled because these movies are soooo good, yet soooo long! Start from the first film released up til now and don't mix em up like my silly friend. Not, not in order like him and he confused himself and wouldn't stop asking me questions lol I've yet to see the new one I'll check it out Tuesday but if this is the best one like people say.. brain fart because the next one will 😩😩will change our lives! I will be one with galaxy lol
