Catfisha movie about the Facebook age and tells a story about identity, truth, love, art and perhaps mental illness. It’s shot in a documentary style and works best if you know nothing of the plot. The suspense builds, peaking on a horse farm in Michigan, and then the twist arrives, bringing a cautionary and emotional denouement too soon. Too soon because, depending on your point of view, it’s either a pitiful story or cynical fable or plain stupid hoax.
