There are multiple Supermen, with multiple histories.
There's Kid Flash from one timeline and Flash from another etc.
The Universe is neither pre-52 nor new-52; it's a mash-up of both, and without having read New-52 it's inaccessible to me.
I can't stand what Marvel has done with their Universe. I keep trying to read more, but I can't.
But just because neither you or I are reading/enjoying Marvel titles anymore; it doesn't mean that they're sucking (not your words, just tying back into the original post).
Marvel are absolutely hitting the younger demographic and gaining new non-traditional comics readers.
That's their aim right now.
Us 30+ year old males aren't the focus, and I'm all for that.
