Still my favorite Nirvana documentary/film after all these years. Conceived by Kurt and finished by Krist and Dave after his death. Given that this was ultimately Kurts project, it therefore by nature doesn't have to deal with the sucide interpretation ect... it sole fucus is to highlight the truly vibrant and exciting world of Nirvana around the bands rise to fame. I watched this probaly more than any other film I can remember. It has humour, intelligence and it rocks.
Most of it is here. Check YouTube for the rest.
