the wrong story

I can accept a world where an illusionist turns out to also have real magical powers. I can accept that this same world was also attacked by an alien dictator. But. My suspension of disbelief breaks when, after that alien basically fried all of Earth's computers, the worst effects of that attack appears to be people griping having to go back to using non-digital cameras. I was intrigued by the idea of this comic-book publisher putting Mandrake, the Phantom and Flash Gordon into one combined reality, but why did they decide it was necessary to throw Earth back to a Sixties technological level? It's a shame. I liked having Mandrake's friend Lothar take on the Phantom's mantle, but I can't believe in that world.
