This collection of American ghost stories/legends features supposed interviews with eyewitnesses and historians, as well as dramatic recreations. The catch here is that it all seems somehow rehearsed and scripted. So, as a documentary, this one gets low ratings.
Even the packaging comes across as pure exploitation, not-so-vaguely referencing the popular TV drama, "American Horror Story". And the "documentary" itself, with a plethora of night-vision cameras, EVP meters, and EMF readers, seems a shallow cash-in on the success of the "Ghost Hunters" and "Ghost Adventures" TV shows. On the positive side, there are some fine locations (like the great Waverly Hills Sanitarium in Louisville, KY), but that's all I can say.
"All American Horror" is a thoroughly dodgy production, and should be of interest only to the most die-hard ghost watching fans. Steer clear.
