Harold and Maude/YMMV

Adaptation Displacement: Hardly anybody remembers or even knows the novel by Colin Higgins, who was originally slated to direct before Hal Ashby came on board. The novel is currently out of print.
Crosses the Line Twice: Boy obsessed with being dead? Funny. Boy who stages his own suicide for attention? Dude, Not Funny. Boy who turns staging his own suicide into a reoccurring act? Funny again.
Crowning Music of Awesome: "If you want to sing out, sing out..."
Cult Classic
Dude, Not Funny: Averted because Harold's pranks are so ludicrously over-the-top.
Hilarious in Hindsight or Funny Aneurysm Moment, depending: The priest's expression when describing Harold's "firm, young body."
- Ruth Gordon, Maude's actress, later hawking the Subaru BRAT. [1]
- Bud Cort portrayed a serial abductor in Criminal Minds who ended up taking away his own life.
It Was His Sled: Surprisingly averted. Although the movie's premise is reasonably well known, the ending is not.
Squick: The priest goes on for a very long scene about this.
Tear Jerker:

Go and love some more.
