I Pukokeki Ioulo Momu/IFYM/Jesse and/or Nuttkase. It should be a person with an extremely diverse taste in movies. This would allow for the moderator's opinion to be better trusted and respected. Nuttkase is a little more particular than average, I would say, but I can personally vouch that he as well as Jesse would handle the forum appropriately.
I think Nuttkase actually (or partially) watches movies for a living lol.
