Personnaly, would've miss something w/o watching this very special movie. And, I even dare to think that it is not only because I am a rock music lover if I am so impressed. What a good idea and a masterpiece of realisation. How lucky are we to be able to have access to such epic stories and feel, to a certain extent, a memorable era in rock music. Also, I was touched by the astonishing and beautiful diversity of all those passionate though fragile people we briefly see there in the movie - interestingly presenting a portrait of their unique experience, from a North American (Canadian and American) perspective. Definitely another good reason to love waltzing - still !!!
