25 best school movies ever

Heathers (1989)

This blackly comic Gen X staple stars Christian Slater and Winona Ryder as J.D. and Veronica, a pair of high school students who undermine the ruling clique of "Heathers" – by killing them off and faking their suicides.

Soon, suicide becomes a trend at the school, with the unpopular kids attempting to top themselves in a bid to join the popular clique. Darkly hilarious.
