Bliss [1985 - Australia] comedy

Harry suffers a heart attack and has a near-death experience that changes his outlook on life. His miraculous return convinces him that there is a heaven but that his life on Earth is hell. His wife Bettina has her worst fears realized when she develops brain cancer from gasoline fumes. His son David deals cocaine and receives sexual favors from his drug-addicted sister Lucy. Harry finds love with a kind-hearted prostitute "Honey Barbara" who kills a top oil-company executive, and then herself, with Molotov cocktails. Shocking scenes include cockroaches bursting from Harry's stitches after his open-heart surgery, and fish dropping from in between a woman's legs onto a restaurant floor. This bizarre and often slow-moving film lampoons the luridness of the human condition.
