Less Than Zero (1987)

Bret Easton Ellis is now best known for warring with other literati and society types on Twitter. But, in the 1980s he was the most shocking voice of Generation X, nailing the blank nihilism of well-heeled teenagers.

The film version sanatises much of Ellis’ debut novel, but watching these awful people slowly destroy themselves at Christmastime does allow for a certain amount of heartwarming goodwill.

Robert Downey Jr stands out as a self-destructive beautiful void putting a mountain of Colombian snow up his nose. Insert method acting joke here.
