Antiques Roadshow appraiser Nicholas Lowry referred to the show as "smart" TV. I think that's a great way to put it. It's both entertaining and educational, while staying true to its form all these years. I appreciate a program that educates people on the history and importance (and value) of fine art, furniture, sculpture, folk art, etc. etc., and aids in the public's collective understanding of how to best care for and preserve our treasures and history. The show offers a beautiful contrast to the hectic life in modern society. It is un-sensationalized, relaxing and educational programming.
I don't believe there is any program that naturally covers as much history and ground in a one hour time slot as Antiques Roadshow. Whatever kind of antiques suits your fancy, there will be something for you featured on the show. I find it to be a great way to educate oneself in a way that is not arbitrary or boring. The shows forum provides a natural way to learn and appreciate culture, fine art/craftsmanship and history. This is public television at its finest!
