Heathers (1988) starring Winona Ryder, Christian Slater, & Shannen Doherty. A pitch black cult classic comedy/satire about a girl who gets involved with a rebellious new kid in town and together they plot several murders they make to look like suicides at their high school. Definitely shocking and ahead of it's time. Also kind of foreshadows real events that would take place around 10 years later. It's on Netflix by the way. 6/10.
