I saw this series exactly 20 years after it was released, but its excellence made the viewing experience timeless.
Carradine plays the immigrant drifter Caine, who walks through the Wild West encountering different situations, people, etc, there was a different plot for each episode. This was more a "Drama" than a "Western" but the interesting sparring moves and Caine's relaxed personality made it a decent alternative to the more violent and rowdy martial arts movies that released around that time.
Whenever this series is brought back to your TV station or one episode happens to be on, it would be an excellent show to tape and watch again and again - if not already released, I'm sure they'll have the show reissued on an official DVD/VHS set.
