What is your favourite documentary, and why?
Never Sleep Again: The Elm Street Legacy, which is a four-hour documentary about the Nightmare On Elm Street film franchise, which includes not only an overview of each individual film and the process of how they were created and made, but also has interviews with the former cast and crew members involved in those films. I'm a huge fan of the ANOES franchise, and knowing that Heather Langenkamp was narrating the entire thing made it so wonderful, because I adored her as Nancy and I love that she still loves and appreciates the franchise. It's a fantastic documentary, and definitely worth watching if you're a fan.
For things not related to specifically fiction, I do tend to watch various programs on the History Channel or some crime-related documentaries like Forensic Files or Lockup, things like that.
However, Aokigahara: Suicide Forest, which is a short online documentary about the legendary forest in Japan, has become a recent favorite of mine simply because it is sensitivity to the subject of suicide, and an understanding from the local Japanese man who regularly goes into the forest to search and help others. I highly recommend checking it out, if you haven't already. It is sad and heartbreaking, but also very educational.
