I largely agree with what he says about the annoyance of the repeated dream sequence of Adamant being conked on the head, but I disagree with seemingly everyone - Adamant himself describes it as cacophonous - about the pop song which is the focus of this episode because I think it's wonderful!
My absolutely favourite thing about this episode is the so-contemporary dress Georgina Jones wears )my second-favourite thing is the bit where Simms has a go at killing her). Frankly I wonder whether this show is a little too much of its time, so that it becomes difficult for subsequent generations to watch and understand. At the time the simplistic moral that the modern world is dangerous would probably not have been welcome to the up-to-date young. A further shortcoming is the repeated playing of the opening of the song, which I suspect was intended to give the hypnotic effect intended in the show, but becomes a bit too much.
My conclusion therefore is that while I love this show, it is open to a number of criticisms. The song is still good though!
