I saw this movie in the early 90’s as a rental, but I think it was from the late 80’s or even the 70’s. Color, lots of yellow and brown. Story follows a young boy, living in a rural dust bowl somewhere, whose friend is murdered. I just remember bits and pieces: a menacing guy who drives around in a black car, the father is under suspicion and may be gay, the mother tries to get the boy to stop wetting the bed by making him drink glass after glass of water and stand in the kitchen for hours without peeing. And I think the father kills himself. Very sparse narrative. That’s all I can remember…
