can anyone suggest some more films like this?

Prozac Nation. 13

 Women, can't live with em; So stuff your mother and live with that.(Bullet Tooth 504)

Apologies if this has already been suggested, but if you like this then you'll love 'The Bothersome Man'... pretty much the same idea but from a black-comic Norwegian perspective

Not a suicide after-life film, but "Defending Your Life" is a unique idea of judgment after death.
