There hasn't been a definitive documentary on the life and times of Kurt Cobain even though it's been more than 20 years (!!!) since the Nirvana frontman's suicide. But filmmaker Brett Morgen has changed all that with the documentary Kurt Cobain: Montage of Heck, an all-encompassing portrait that tracks Cobain's brief life from a troubled childhood, to his rise to fame, to fatherhood, all while exploring the darkness that eventually swallowed him whole. As you'll see in the film's first trailer, Morgen uses a combination of animation, home video, archival footage, and testimonials from those who were closest to him, to show Cobain as he was: a troubled genius who just wanted to be normal. Given that this was produced by Courtney Love and their daughter Frances Bean Cobain, you can probably consider this film definitive. Check out the trailer below.
