Well, I was just making conversation. My initial point is you would think everyone would've heard of real superheroes in the recent past, Christopher was making the point that some young people hadn't even heard of the Beatles which I think is a false equivalence (however cute it is to equate the Beatles with superheroes).
I hear you. Young people can be very ignorant, but not THAT ignorant. Whenever someone says, "that movie was before my time," I ask them if they ever saw "Wizard of Oz." When they say yes, I explain that no movie is before their time.
But in a world like this, I could see the point that superheroes would be more famous than just about anyone but the President.
I think this show could benefit from more world building. Why would the ISA really disappear after they win the final battle? Where are the other superheroes of this world? They do exist after all, since we see one of them chilling as a janitor.
Shining Knight can't be all that's left.
Is there a Justice League on this world? Is there a Superman? If so, is he a colleague of the JSA as he was in the comics' Earth 2, or is he decades later and just coming around in the aftermath of the JSA's disappearance?
Are there other villain groups? You would think there are.
There's no reason all characters we know couldn't be fair game.
Except of course studio stuff.
