For the most part, Rotten Tomatoes seems to have its finger on the pulse, at least when it comes to quality. Every rating portal has its flaws, but we all need a reference of some sort. When it comes to documentaries and the recording of human behaviour, here are the best ones according to the folks running the fresh-o-meter.

1. Man On Wire - 100%

IN 1974, daredevil Philippe Petit walked between New York's Twin Towers on a thin wire, and this is a 2008 documentary of that feat. It tells of the immense planning that went into getting it done, and keeps you on the edge of your seat throughout.

4. Blackfish - 98%

This 2013 documentary film directed by Gabriela Cowperthwaite tells the story of Tilikum, a captive killer whale. Humans and performance killer whales have a storied history, and this film looks at how we understand very little of these creatures. Basically, it's a total takedown of places like SeaWorld.

5. Exit Through The Gift Shop - 96%

6. Kedi - 98%

This 2016 Turkish film directed by Ceyda Torun is a step away from usual direction that documentaries take. It's about the 100s of thousands of cats that roam the metropolis of Istanbul, how the locals live around them, and the frantic modernization of an ancient place with a unique feline history.

7. Waltz With Bashir - 96%

This heart-rending 2008 Israeli animated war documentary was directed by Ari Folman. The film tells the story of Ari himself trying to recollect memories of the 1982 Lebanon War, in which he served as an infantry soldier. This one is not for the weak of heart, but it is truly masterful.

9. Anvil! The Story Of Anvil - 98%

This Canadian rockumentary is about a heavy metal band named Anvil that released an album in 1982. This album went on to inspire and influence everyone from Metallica to Anthrax, yet Anvil itself dropped into obscurity, consistently touring and suffering the rigours of the road without ever finding fame. It's comical, touching, and surprisingly emotive.

10. Project Nim - 97%

This 2011 British documentary focuses on a science experiment from the 1970s that involved a chimpanzee named Nim. The basis of the project was to establish that an ape could communicate through language if raised as a human child. However, it soon devolved into a heart-wrenching indictment of how terribly humans treat animals in the name of science.

13. Citizenfour - 96%

This 2014 documentary film directed by Laura Poitras was one of the first to have direct contact with Edward Snowden after the NSA spying scandal made his a notorious figure who was constantly on the run.

14. Wiener - 97%

This documentary chronicles the life of the charismatic and headstrong Anthony Weiner, as he runs for mayor of New York in 2013.
