As an old fan of Ganja & Hess, i was very curious to see Spike Lee's take of this arty oddity.
Very few things changed from the script, except the part of minor characters : the slow pace, the theatrical acting and the general mood are scrupulously respected, so you must expect an art-et-essai movie rather than an usual vampire flick.
I didn't found it as bad as the other reviewers, even if I can express a few reserves : the score that sometimes looks like a sort of car play-list (the original was quite experimental), or the lack of twisted shots that made the first movie so unique.
However, I hope that it will encourage the new generation to rediscover the 73 version that still shines like a black diamond, with its strange mix of perversity and religious knick-knack.
