"The happy ending, like all clichés, is hard to define. I used to believe all happy endings resemble one another, while every unhappy ending is unhappy in its own fashion. But that will not do.
On the basis of two current films, the splendid "The Two of Us" and the so-so "With Six You Get Eggroll," I've decided there are at least two kinds of happy endings: the mechanistic and the organic.
The mechanistic happy ending is simply the regular Hollywood ending we know and love. It bears little relationship to what has gone before. Doris Day may just have dumped Brian Keith in the middle of the street in his underpants, but he will somewhere borrow a Good Humor uniform and they'll be together again, in love again, all misunderstandings cleared up.
This sort of ending is simply a mechanical arrangement of characters, designed to reassure us.
