What documentaries made you feel good, or were just fun to watch?

I think documentaries for the most part have done a good job telling stories of real life events, However I always feel their are so many gritty, powerful, dramatic documentaries that a lot of them lose their touch. Seeing other documentaries that are fun give this genre some new breath. I argue stuff like "being Elmo", "finding Ms. Locklear", and "Jodorowsky's Dune" really are amazing to watch and easier to watch. Again, not against those documentaries that are hard to watch, theirs just so many.
