Query: Everybody's a critic, but some get paid for it

I've purchased Leonard Maltin's book annually as long as I can remember and find it to be an invaluable resource. I am a fan of Mr. Maltin's, and find his reviews to be interesting, well-thought out and, occasionally, hilarious. That he gets blasted by some for his reviews is amusing; all criticism is ultimately subjective. Because he doesn't like 'Blade Runner' doesn't make him an idiot; I didn't like it, either! The best film critics give the prospective viewer enough information to draw their own conclusions from the criticism; Mr. Maltin and Roger Ebert are both experts at this. I highly recommmend books by either of these film critics.
