I just finished the second Superman book and it was OK. Better than the first, but still...I can't figure out what it is about these books that I don't like. I think it's just that...and I'm not sure I'm explaining this like I really want to...they are just super long monthly comics. I would expect important, huge, major, world-changing things to happen in these books. But they aren't anything special. It's just a monthly that's 5x longer than it needs to be.
I think the problem is that now I want every Superman book to build off of All Star Superman and I've not read a Superman story that comes anywhere near that as far as getting the character right. Earth One is just emo Superman. He's not likable and he's not really someone that you'd look up to. He does heroic things and he's a good guy, but it's like it's a struggle or something for things to happen. In All Star Superman, literally every thing he did as Superman and Clark Kent both was an amazing good deed. I don't like Clark Kent struggling to fit in by getting bad grades or come up with rent or anything like that. Superman is supposed to be beyond that kind of stuff.
