Amy (2015) remains one of the most intimate music documentaries ever made, its power rooted entirely in Asif Kapadia's masterful use of home video footage. The Academy Award-winner for Best Documentary Feature chronicles Amy Winehouse's meteoric rise and tragic decline without talking heads, earning over $23 million worldwide.

The Act of Killing (2012) is the most audacious documentary ever made, using cinematic reenactments to force former Indonesian death squad leaders to confront their crimes. Over 90% of the film is improvised or genre-based, revealing an unsettling pride in mass murder that completely outperforms #10 Senna in psychological depth. The banality of evil is captured as perpetrators gleefully recreate executions in musical numbers—a technique that won the film a BAFTA and an Academy Award nomination.
