In starting this theme in the horror genre I was glad to have found this film online. This was one of my favorite discoveries of 2011 and well worth viewing. My thoughts from back then were:
I remember after I saw this film I tried to remember where I first heard of it: it was in Stephen King’s non-fiction book about horror Danse Macabre. He listed it in an appendix as one of 100 excellent horror films released between 1950 and 1980 or so. I agreed with his assertion immediately. It’s a jarring film but brilliant at both ends so to speak.
