Granted, non-fans of Neil Young will not like this film, but as one of his biggest fans (I have over 35 CDs of his music, solo and with CSN, Buffalo Springfield and others), I loved this film. Many people were put off by the grain of the Super 8 sequences, but I think that visual scheme ADDS to the mood and feel of his music.
I also liked the varied song list. Not only does he play songs from his most recent album of the time (Broken Arrow, an OK, but not great album) but he revisits his classics (Tonight's the Night, Barstool Blues, Like A Hurricane). It's a great sampler.
I also liked the weird humor that Young and Crazy Horse infuse into the documentary sequences. Many people were understandably turned off by this (including my mother and she LIKES Neil's music!)but I thought of it as in the Frank Zappa-vein of bizarre personal humor that only a handful of people fully get.
NOTE: If you buy this film, purchase the Canadian import version. It is presented in widescreen format (1.77:1 not 1.66:1 as listed in technical specs) The USA Films release is panned and scanned and believe me Jarmusch makes the most of the frame, no matter how small it is)It costs more, but believe me, it's worth the extra money!
