Callan was one of my favourite TV shows when I was a kid, and having recently watched all the surviving episodes (British TV companies in the 60s and early 70s had a habit of recording over shows in their archives due to the high costs of the tapes, hence the loss of certain episodes of Callan, Doctor Who, et al) is one of the few shows that not only is as good as I remember, but is actually better now that I better understand its themes. 👇🏼
