I agree; "Flesh For Frankenstein" is a masterpiece. Have you seen this in it's original widescreen format? It is beautiful and mind blowing! I was thrilled to see that the Criterion label has also recognized this as an important film, and have released a beautiful, restored print. With the exception of 1933's "Bride of Frankenstein," i believe this 1973 film is the best film about the mad Dr. Frankenstein.

Having been a nasties fan for years and even enjoying Bloody Moon I decided to finally watch this film. What a load of rubbish !! So tame it's unbelievable ! Give me Argento or Fulci any day !!!!!!!
