Father and Son (ITV1, 9pm)
If you’re in the habit of occasionally picking up a newspaper or switching on theTV, it can sometimes seem that there are so many guns on the streets these days that they must be coming free in cereal boxes. It’s clear that escalating guncrime on Britain’s streets is fast becoming one of the biggest problems in society. The only positive to be taken from this worrying state of affairs is the great drama that the situation is producing. Father and Son is the latest drama to explore this seedy world.
