Nothing mindblowing about it. It's the same bullshit DC has been doing since they used that Brainiac 13 crap to make Metropolis look more like it did in STAS (which was, what, on its last season or something?), retconned Superman's entire origin so Luthor's backstory fit in with Smallville (even though nobody with a brain watched that shit) and had a Kryptonian boy conveniently drop out of the sky so Superman could have a son like in Superman Returns (which rocks and you all suck, shut up).
Yeah, not really new. Superman flying, kryptonite, Batman's all black costume, Harley Quinn, Mr. Freeze's Nora backstory. All things started in other media that wound up being adopted by the comics. Film, TV, and radio have always had more influence on the comics than the comics did them.
