I hate endings. Never liked them; in books, films, sometimes songs (especially fades -- what the hell is that?), whatever. This is why my novel has a shitty ending. And I took a lot of guff for that. But it was a sort of my way of protest against "the ending", seemingly so tacked on and trite, unrealistic stuff.
The grand exception to this is the 1967 film masterwork, The Graduate, which has been without challenge since I first saw it at age 19 my favorite movie of all time.
