Well that was a silver age comic all right.
For a Silver Age comic is was enjoyable. Had some of the trappings of such… heroes acting like quasi-jerks for no real reason. (Seriously, how insecure are Flash and Superman to be mad someone helped them) convenient powers to save the day out of nowhere (admit didn’t read many early Martian Manhunter comics but since when could shape shifting into a superhero give him their abilities, and Martain Science made the Gold K useless, that’s convenient)
Also the scene that we later find out is Superman discovering the villains are on their home planet… I get they were hiding the reveal but the way they did it I thought the comic reader skipped a part or something. I mean, did Superman just let the Volcano erupt?
Didn’t figure out it wasn’t the real villains though, and unlike a lot of twist from the silver and bronze age that one did actually make sense. So kudos.
All in all a decent story, a product of it’s time for sure but I enjoyed it for what it was.
