I remember The Professionals from my childhood. Just watching the opening credits is enough to take me back! The amazing thing is that it hasn't lost any of it's entertainment value.
The Professionals are three characters, Cowley, Bodie and Doyle. They are part of a counter-terrorist and counter-criminal team known as CI5. The stories are often based around finding a hitman or stopping some kind of terrorist attack. This gives The Professionals a relavence today. Indeed it also shows us that the world hasn't changed so much - apart from the TV being more entertaining back then!
If you've not seen The Professionals before, you like cop shows and you are not crazy about being politically correct, then you'll love this.
