The unbelievable strangeness inherent in truth has made for some incredibly destabilizing documentaries about the blurred lines of fact and fiction. Films like “Dear Zachary,” “Catfish,” “Exit Through The Gift Shop” and “The Imposter” all blow themselves up in the middle all featuring “oh shit!”-like twists so disarming, so surprising they make one question the very reality and existence of what you’ve been watching. So, prepare to be fooled, thrilled and surprised with a new classic of this upending subgenre with “Untitled Amazing Johnathan Documentary,” a doc that uses the integral subject of magic and artifice to create a riveting meta-story about the illusory nature of truth, trust and the self-examining questioning of what you thought to be real.
