i think the problem with geoff johns, especially with this story is that, he isnt trying to think of an orgin that would fit in with continuity,rather, he just seems like he's saying wouldn't it be cool if i did this or this or this. Good review by the way
I have to disagree. I loved this book. It's much better than any other origin story- Earth One was too dark, Smallville has it's moments, Superman: The Movie is out dated, Birthright was great but didn't follow much of Superman's career, and TAS is in the past. I'm pretty sure it was supposed to be on it's own continuity wise. Not sure why you heard otherwise.
So basically what your saying is that it's because because better stories are old?No it's not and never was meant to be it's own continuity it was meant to be and sold as the new canonical origin story just like Green Lantern Secret Origin
