The analysis makes a lot of sense. My only quibble is that he suggest omitting Episode I entirely, which is a great boon to humanity *but* loses the best single piece of music in the whole series. I mean, let's get real -- the only reason I cared about going to see Episode I was the video trailer of Duel of the Fates. Terrible movie, but it's John Williams' masterpiece in my book.
(And I find myself put oddly in mind of Narnia by the whole thing. The order he argues for is, in many ways, very similar to my preferred reading order for Narnia, with The Magician's Nephew just before the final book. I suspect he's right that it works, and for some of the same reasons.)
Anyway, I am almost tempted to organize a Star Wars Day at some point, just to try this out: it's been enough years since I last saw them for my palate to be reasonably clear. Maybe one of these days. (Higher priority is the Batman party that I need to hold sometime in the next couple of months, before the next movie comes out...)
