I thought it was super good, although incredibly depressing. I'd always been super skeptical about all the conspiracy theories surrounding his death, but after hearing/seeing his journals entries and shit, it seems pretty obvious that the most logical explanation is the dude did in fact kill himself.
My only complaint was I thought they went a little overboard with the crazy visuals/montages. They felt kind of pretentious at times and made it hard to distinguish between what was Kurt's art and what wasn't.
All in all, two thumbs up from me - would recommend to a friend.
Oh, and I heard rumors there would be an updated version with Dave Ghrol.. anyone know if theres any truth to that?
