U2 are the ultimate marmite musicians. If you love 'em, you really love 'em, and vice versa. For me, some of their tracks are very good, but sometimes the 30-year-long collection of plaudits they've received can be very annoying. I mean come on, give someone else some credit! But this is an OK documentary/concert movie, charting U2's blues-rock phase, and particularly interesting considering this was only three years before they entered their euro-dance influenced midlife crisis phase with Achtung Baby.
