The turning point of the film is when Robin Williams weeps for his dead son, who is graphically hanging from a strap around his own neck, having accidentally killed himself while masturbating over pictures he took of Robin Williams' girl-friend's up-skirt panties during dinner the same night (graphically shown).
It's booked as a comedy.
Robin Williams' character, fully in shock, then fakes a suicide note, cleans up his son's privates, moves his son's dead body to hang in the closet instead of by the bed, kisses him on the forehead -- and THEN THE COMEDY ENSUES! Wheee.
Nobody should see this. To say it has a redeeming quality is to fail to see the failure inside of the "inside dark humor". This is not "Heathers" -- everything I described to you is graphic -- as is the discussion earlier on between the son and a friend regarding scatalogical sex acts -- men defecating on women in pornography. You decide.
