To put yourself in SBP's shoes (well, I'll try.
this will take a while!)... Imagine being a normal boy who loves reading comics. You become a comic book character, literally. Super-
friggin-boy! This is
so much cooler than a wet dream, you think. Then Earth
dies and you get sucked into a world of paper and ink (aka the DCU). Now
that must be the most lopsided, bittersweet dream ever. You team up with the gods of modern mythology. Well, that
still doesn't compensate the loss of everything before the
brouhaha, of course. But the reward is sweeter. The DCU treats you with a front row seat in its theater (aka Hotel Paradise Dimension). Once the movie being played approaches the first of many climaxes, it starts to suffer from big editing gaffs. The characters you loved go whack or die. How unnatural... it's a
Casablanca turned
Gigli! Maybe you should've been sucked into Earth-616 instead. In a fit, you punch the friggin' screen! Holy wow, now you're the master of the 'Fourth Wall'! Well, if your life's sole purpose now is to watch a fantasy world existing behind that 'Wall', you want to 'make it right',
right? Just like some crazed fanboy barraging DC with petitions, but
you do it much faster. Yeah. Now you go kill'em like you're doing emo things to your childhood toys. And why are they so powerless? It's
your little fanboy dream, remember? Them fictional characters wouldn't leave a
mark on your holy impenetrableness. And then you kill Conner Kent as if both of you are competing RPG players. Soon later, someone whose powers are above your big
sucker-punch of destiny flings you to the future. Heh... and you thought this was
your personal lucid dream. Unfortunately, you are now really sick in your mind, even in Earth-Prime (aka IRL) standards. You've hacked your favourite video game into corruption and now you can't even play with it. You should be waking up anytime now, but your body keeps telling you that it isn't over, just play along now... So it's time to keep on killing, but now just doing it for the lulz. Dun-dun-dah! Watch out, Legion! It's not just Kara who thought she's dreaming you guys!
See how complicated it is? It ain't no nutshell. Geoff Johns should be winning every Harvey and Eisner just for his ingenuity in adding such sophistication to this, uh, one-dimensional character. (A bit ironic, but I hope you'll take it.) That's why I sympathize with all those DCU characters on an extreme scale (and probably any other comic writer who would've dealt with him but S!, Wolfman & Johns).
