"It is just a coincidence that the first time I saw Michael Lehmann’s Heathers (1988) was within hours of the first time I saw David Lynch’s Blue Velvet (1986), and I immediately made comparisons between the two films which I may have not noticed otherwise. More people are quick to compare Heathers to the work of Tim Burton, because of the associates he had on the film (producer Denise Di Novi and star Winona Ryder, to name but two) and the fact that the candy-coloured suburban setting mirrors that of Edward Scissorhands (1990). But the picket-fenced world of Blue Velvet equally does so, and preceded both films, and only Blue Velvet matches Heathers in its extremity at portraying unusual characters, and capricious changes in editing and tone."Heathers is currently available to stream at Netflix, incidentally.
