What happens when you see Martin Scorsese’s No Direction Home: Bob Dylan a second time? (My first exposure was in the Varsity 8 last Friday at the Toronto Film Festival.) This masterful doc, which I saw yesterday on the Paramount Home Video DVD, gets a little bit better because the basic theme seems that much clearer, and the half-ecstatic, half-tragic arc of Dylan’s experience from ’62 to ’66 is that much harder to miss. Dylan’s basic motto/game plan was to always live and work in a state of becoming — no standing still, no looking back, always the next thing, etc. This was the basic mindset that led to his early-to-mid-60s genius run. It was what took him to the top of the plateau, and also what enraged his folkie fans to the point that many of them wanted him pushed off when he went electric. The extras are cool (full-length clips of Dylan singing this and that song, four or five tribute numbers by other artists) but the coolest thing about it is the slight but distinct improvement factor which, after all, is what happens with all great films.
