2. War of the Roses (1989)
War of the Roses is a black comedy starring Michael Douglas, Kathleen Turner and Danny DeVito about a seemingly perfect couple whose marriage falls apart, leaving them in a nasty war over their material possessions. The level of hatred increases throughout the film and the malicious humiliation ramps up cars are crushed, dogs are (nearly) made into pate and eventually with all possessions destroyed thoughts of homicide appear.
Why is it anti-love? Hatred seems to creep up on the Roses showing that something that seems perfect to begin with can degenerate and thoughts of love can turn into thoughts of homicide.
Most anti-love moment? The very last scene is so completely anti-love that Cupid must die a little inside every time someone watches it.
