Great movie. Well worth catching. Misses out on a quite a big part of his real history (for example I don't think that his 45 on Impact is even mentioned), so a bit flawed from a "documentary" point of view, but still a very nice piece of work.
I love Rodriguez material, both of his LP's on Sussex are very good, especially the second one ("Coming From Reality").
It's a swedish guy that directed the movie so it has been getting lots of exposure here in Sweden. Quite amazing that it's been nominated for an Oscar, and even more amazing that Rodriguez career has gone, if not from 0, then from 5 to 100 in a couple of months. The attention his music is getting is well deserved and long overdue.
