One of the most iconic Western series ever. It's the longest running western series and one of the longest running dramatic series (1955-1975). I've see all 635 episodes some years ago and they are still running them on TV. IMHO, what makes the series so popular is it's characters, Matt, Doc, and Kitty, all of which have won multiple Emmys. The list of guest stars is amazing. Although some of screenplays are rather dull, some are amazing.
