I absolutely love this movie. It has so many different levels to appreciate. Besides the main twisted storyline that should make any cult movie lover wriggle, there is an interesting use of colors in the film (bright pinks, neon yellows, etc) that reminds me of the Dick Tracy movie. It is also just full of catty one-liners that my friends and I use all the time (i.e., "I know what it's like when a girl needs her prescription filled." and "Ms. Koombs is less aware than the chair that you're squirming in now."). With the strong sexual themes and partial female nudity, I often refer to it as an "art film". I have watched this movie over thirty times, and I still find new symbolism and hidden meanings when I view it each time.
I feel that this movie would especially appeal to fans of the John Waters films (Pink Flamingos, Female Troubles, Desperate Living, etc), but if you're offended by sexual discussions involving drag queens and lesbians, this is NOT the movie for you.
