Recommend some movies similar to Requiem for a Dream, Trainspotting, and NaNa, which reflect human nature, preferably without love.

The 3rd Floor is very superficial, only seeing the surface and not understanding the deeper meaning of the movie

I recommend the following movies:

He grew up under the overprotection of his mother and lived a life of depression, eventually turning to drugs and falling into a state of madness.

Roger is the main creator of "The Wall". His father died in World War II. He poured his feelings toward his father into the album, as well as the loneliness he felt after losing his father. Pink's adult life is basically a portrayal of original lead singer Syd Barret. Roger Waters, David Gilmour, Nick Mason and Richard Wright combined these life stories and finally created the mysterious album about the hallucinatory journey of the male spiritual world - The Wall.
