I like DVD extras. I like shows about how things are made. I like to know what goes into making a work of art, a building, a city, a ship. This DVD is along those lines. It's a very good behind-the-scenes of an iconic 1980s album from one of the most important bands (love 'em or hate 'em) of our time. Surprises include how many layers each song has, how insecure Bono clearly is, and how opportunistic these artists have to be to capture lightning in a bottle.
