Crimes and Misdemeanors

Last night I had insomnia. I thought that if anything would cure it, it would be watching the unfinished movie I started the preceding afternoon. Woody Allen movies run like straight dialog; the scenery is meaningless and useless. If you only listened to the whole movie you wouldn't miss a thing, unless you happened to deeply appreciate the sight of New York City buildings and lackluster costuming. Someone once told me "Bullets Over Broadway" was one of the greatest movies ever made. How could that be? Someone else told me "Crimes and Misdemeanors" was his all-time favorite movie. How could it be?
Amazingly, finishing "Crimes and Misdemeanors" from 2:45 a.m. to 4 a.m. did not put me to sleep. The movie ended, and I felt sorry for all the characters' plights at the end. If I remember correctly, "Bullets Over Broadway" ended in bullets over Broadway, and, in other words, a very unhappy ending. Since I was fully awake and it was only a few hours ago, I remember that "Crimes and Misdemeanors" ended with the commission of crimes and misdemeanors. Why does negativity result in critical acclaim? Why can't the story end in some semblance of hope for the future? Something funny to leave you amused and hopeful at the end? I suppose we're supposed to erupt into fits of laughter at all the witty banter and pessimism that fills Woody Allen movies. I suppose that, maybe, he's made so many movies that, after awhile, all that negativity is expected and appreciated and passes for profundity and intellectualism because it is repeated often enough.
Why do people like Woody Allen movies? I keep watching them, hoping I will find out.
