I finally saw this cult classic from the late eighties. Watched it from an old VHS, and over at Facebook a friend said that it's a film that just has to be watched from VHS.
There is indeed certain charm that only low-budget 80's flicks have. But that aside, this is a neat quirky little film that has lots going for it: young Winona Ryder and Christian Slater with their snarling accents, taut script by Daniel Waters (I believe he won the Edgar for the script) and funny late eighties' costumes. The story about two high school lovers who start killing their school mates is twisted and funny. Slater's behaviour is never really explained, which is a good thing, since it might've been awkward. There are also some implausibilities as comes to the behaviour of Winona Ryder's character and her behaviour. The ending with Ryder starting to befriend the high school fatso didn't feel right, even though I can see why they did it that way.
Nevertheless, this is a fun film that hasn't dated badly. (More Overlooked Films here.)
