I watched some of the original show starring Edward Woodward when it was on originally, but have not seen it since. It apparently ran to 88 episodes! I have not seen either movie. Vigilantes to be a popular theme in TV and movies. I guess that unlike a police show you do not need a big regular cast and people like to see someone dealing with criminals who seem to escape justice.
I had not heard of the new show, but I have a few things to watch lately anyway.
