Cities should be a celebration of the human spirit according to leading Irish architect Sean O'Laoire. But are they? This four part series takes the lid off our leading cities and finds out what makes them work, or fail. The first programme in the series focuses on Dublin where 40% of the country's population lives. Builder and developer Mick Wallace, city planner Dick Gleeson, Docklands born singer Shaz Oye and Dublin footballer Collie Moran explain what they love and hate about the city.
