This was hands down my favourite TV series as a child. It was probably the first time I've ever been a fan of anything. I can still recall bits and pieces of some episodes even now!
I didn't have any problems comprehending the story lines, as far as I remember, so the other comments saying it's dead simple must be right. But while the series might seem dire for grown-ups, it was pretty impressive for children.
I would love to see this again just to see it from an adult's point of view, but I won't retract my comment that it's a very enjoyable series in its simplicity, and is a beloved personal memento of my childhood.
