I think the genius in Gummo is that there aren't different tragic or comedic scenes, but EVERY SINGLE MOMENT in the film is tragic and comedic at the same time. Instead of being forced to run back and forth forever between grief and high delight, the film engrosses you in an unsettling, poetic, nightmare dreamworld. It's a love story about the absence of love, it's a film about the void when love is gone.
