Although offering glimpses of the silver age, this story is still one told very much in the style of the golden age. The setting may be futuristic and science fiction like, but the story itself and the the characters have the usual "internal dialogue to explain the plot" type of approach that is consistent throughout much of the period. The only difference here is that the characters aren't exactly throwaways, instead this is the first appearance of the original three characters that would become the Legion of Super Heroes. As a truly pleasurable experience, this falls a little short, but in terms of comic history, it becomes a bit more readable. The enduring characters have an innocuous entrance to comics, but to this day they still remain reliable properties of DC.
