From the writer and director of The Best Little Whorehouse in Texas (1982), here you have an even weirder piece on sentimental (and sexual) liberation: Harold and Maude (1971, Hal Ashby), a love story and life lesson neatly packed in total eccentricity! You are welcome!
While Harold's coming of age is the linchpin of the movie, he does that through his experience of meeting and getting to know Maude. Oh, Ruth Gordon, oh! At last, an inversion of the empowerment-through-romance-with-men we have seen so much (as in here, here, or here).
The special pluses:
+ Life is long and people can enjoy it at all ages!
+ And we are sexual, sensual beings at all ages!
+ Intergenerational love exists. And is also sexual.
+ The movie is a cult classic with very peculiar and most awesome esthetics. Rookie even suggests ways how to bring Maude in your warderobe.
