I remember when they announced that all 6 Star Wars movies were going to be available on Blu-ray at the same time and I had a little bit of an internal conflict about whether or not I would introduce the franchise to my son starting with A New Hope or with The Phantom Menace.
It didn't take me long to decide that the Original Trilogy should come first. Chronology is nice, and everything. But my love of Star Wars is based around a certain experience or feeling I can't quite articulate.
This video helped give that feeling meaning...
The prequels are fine, but the Original Trilogy always comes first.
