I caught these back to back on either TCM or AMC, when they were good, many moons ago and found them to be very entertaining. I caught the end of Werewolf again when it was on MST3K too, back on the Sci-Fi channel I believe. As goofy as they are there's certainly a charm about them and with their brisk pace they stay interesting. Frankenstein makes kind of a beef cake out of the monster too, so I'm sure that helped get the ladies in the mood for some back seat action at the drive-ins. These two remain iconic in my mind of typical drive-in trash, there's probably no other movie I'd want to see more when sitting in a hot rod. The follow ups How to Make a Monster and Horrors of the Black Museum have both been out for awhile now, yet neither Werewolf or Frankenstein have made it to DVD in any region. Even crappy knock offs like Frankenstein's Daughter have made it to DVD. Is it just too obvious of an idea to put these out as a double feature for Halloween?
