While fans of horror might not necessarily learn anything new from watching this documentary, they'll definitely enjoy the time listening to their favorite directors, producers, and alike's, input on classics of the genre as well as what inspired them to be apart of the films that they did. The movie begins with horror in its early days of cinema and works its way up to modern day, showing us what the title suggests it will: "The Evolution of the American HOrror FIlm." Again, while you might not learn anything new, this documentary gives us the opportunity to jump into the brilliant minds of some of those who made some of our favorite films, and for that I am grateful. Worth the watch!
