Escape from Future World has a very limited audience, typically boys in first or second grade.  Superman is a familiar action figure and if this is what it takes to get them reading, then so be it. The brief summary on the reverse title page pretty much sums up the whole story:  Superman and Cyborg are sent into the future by evil villain Brainiac and they figure out how to escape and destroy him.  Simple drawings, simple text, simple story, not much excitement.
