This was an oxymoron feeling (in early 70s) - both of excitement and horror, like the one in a zoo serpentarium. Also, it was the second encounter with Tony Musante (after his satanic role in "The Incident'') and an acquaintance with Scott Wilson, whose rendition of an Innocent mentally deranged savage character was beyond compare. The film echoes when one is faced with inhumanly perilous situations. Yet, the resistance to going through its horrors again prevails. Great film anyway.
