The Edge is kind of the odd man out in this. Page and White are very based in the blues, which The Edge really isn't.
You get a lot of insight into the creation of the band, and the creation of The Edge's sound.
Of the three, The Edge is the one who drives himself places, the other two have drivers. I find this very amusing.
It is well worth seeing, especially if you make music. The enthusiasm of all three is amazing (even if The Edge's is a little low key, but then again he is a little low key).
The parts when they all play together are astounding.
