Love this show. Started a blog about it.
I watched this show as a kid in reruns and loved it. Got the chance to reconnect with it when it came out on DVD. I was so thrilled with it I started a blog about it, here:

Understand, it still seems a little dated and doesn't compare in terms of action by today's standards or even by the standards of the best kung fu movies of the genre. But it was just a great show, an inseparable part of the 1970s kung fu zeitgeist. Highly recommended on that basis.
