This is a golden age for film criticism. Never before have more critics written more or better words for more readers about more films. But already you are ahead of me, and know this is because of the internet.
Twenty years ago a good-sized city might have contained a dozen people making a living from writing about films, and for half of them the salary might have been adequate to raise a family. Today that city might contain hundreds, although (the Catch-22) not more than one or two are making a living.
Film criticism is still a profession, but it's no longer an occupation. You can't make any money at it. This provides an opportunity for those who care about movies and enjoy expressing themselves. Anyone with access to a computer need only to use free blogware and set up in business.
