I have little to add to Eugene Kim's comments which accurately express my opinion, too. In the 1970's, this odd film ran on late night television and stood apart from most everything else. Peter Medak's director credit for The Ruling Class preceded him so I was very patient with this film. The momentary use of piano music was an immeasurably extreme highlight. I felt very friendly toward the unique Glenda Jackson who was intensely committed to her acting, her director and her cast-members. For all its, what, its stupidity? ... For all that, the film achieves a believable sense of intimacy sealed from the world, hence the sense of suffocation. This film is capable of leaving a lasting impression because of the committed cast and those few moments of piano music.
