Q & Q, the exciting youth television series dating from 1974, broadcast by KRO, attracted some four million viewers weekly. In the main roles Erik van 't Wout (Aristides Quarles van Ispen) and Martin Perels (Wilbur Quant). Also, Bob Long (grandfather of Reinier Quarles Ispen) played an important role.
I gave the series an 8, but that is more from the nostalgic feelings that this evokes than that I still know how to interpret it exactly. It has been a long time since I have seen this and I have no idea if this will still stand if I watched it again now. By the way, I came up with this because of the announcement of the new Apple + series Home before Dark ;-)
