Old TV series, including westerns, have been put out on DVD, or on YouTube or in reruns on third-tier TV stations.
It’s enjoyable seeing some of the actors, especially ones who have gone on to movie fame (or just gone on), even though the shows seem more formulaic and the plots more predictable. Some of the fashions, hairstyles, and dialogue of the 60s and 70s are a lot more outlandish than I remember when I originally watched the shows.
Tell ya Wagon Train actually holds up against most of this modern stuff they have on tv today. Love seeing old episodes of The Equalizer when I can find them.
