My review is on the colour series as I've not yet watched the first two b&w series, but the fact that they were so popular they led to a successful public campaign not to end the show after Series 2 as originally planned, and long before the days of social media, means they must be good! I can say the next two series were extremely good, equating to one of the highest quality TV dramas I've ever watched.
The best episodes, and there are many excellent ones, are tightly written gems of intrigue that if you missed a minute of you might lose the plot, which turns and twists like a poisonous snake. It's very surprisingly hard hitting for a 50 year old show, it's made for adults and is all the better for it. This is of course a major reason why it's so popular with fans and so highly rated.
The casting and resulting acting is top notch, it made a star of Woodward here, whose star eventually and rightly shone in America, after a long career outside the A List. Callan's scruples and doubts are as enthralling as the Cold War plots of Red Files on Russian agents and his methods of dealing with them, sometimes coldly and ruthlessly, sometimes cleverly, and not strictly to orders.
Another highlight is the relationship he has with his colleagues, all of whom are in a strict hierarchy, one or two of which he dislikes far more than the targets he's asked to do a job on. The favourite for me is Cross who appears in most of the colour series, superbly played by Mower, a very under rated actor, who portrays his seething dislike of being under Callan, because he comes from a higher social class and in Military terms, where most of the agents are picked from, would have been an Officer to Callan's Corporal. Highly recommend others watch the repeats now showing on TV or get hold of the DVDs. IMO the most compelling espionage TV show of them all.
