Not A Comedy`
I just rewatched the movie last week and have realized this film has been miscategorized for decades. It is not a comedy. Sure, Danny DeVito offers comic relief, and there are some laughs in the bickering and escalating one-uppances, but this film is actually a more serious, subtle and ultimately sad commentary on a doomed marriage.
And Kathleen Turner's hatred is palpable in that last scene when she brushes away Michael Douglas' hand. Still gave me a shiver more than twenty years after!
