He then goes on to present a variation on this, the "Machete Order," in which you watch them as was just laid out but skipped Episode I altogether.
"George Lucas has done everyone a favor by making the content of Episode I completely irrelevant to the rest of the series. Seriously, think about it for a minute. Name as many things as you can that happen in Episode I and actually help flesh out the story in any subsequent episode. I can only think of one thing, which I’ll mention later.
Every character established in Episode I is either killed or removed before it ends (Darth Maul, Qui-Gon, Chancellor Valorum), unimportant (Nute Gunray, Watto), or established better in a later episode (Mace Windu, Darth Sidious). Does it ever matter that Palpatine had an apprentice before Count Dooku? Nope, Darth Maul is killed by the end of Episode I and never referenced again. You may as well just start with the assumption that Dooku was the only apprentice. Does it ever matter that Obi-Wan was being trained by Qui-Gon? Nope, Obi-Wan is well into training Anakin at the start of Episode II, Qui-Gon is completely irrelevant.
Search your feelings, you know it to be true! Episode I doesn’t matter at all. You can start the prequels with Episode II and miss absolutely nothing. The opening crawl of Episode II establishes everything you need to know about the prequels: a bunch of systems want to leave the Republic, they are led by Count Dooku, and Senator Amidala is a senator who is going to vote on whether the Republic is going to create an army. Natalie Portman is called Senator Amidala twice in the first 4 minutes of the movie, so there’s no question of who’s who."
You might not agree with everything he says, but it's interesting stuff. Read the rest here.
