Actually, everyone was steadily losing their powers at the moment, so no one was just as strong as a 16 year old during the fight.
But these are all just dong-measuring power arguments ("Uhm, clearly, historically, Kal-L has been shown to have a bench press capacity of blahhhhhhhhhhhhh0010010111001" "SKEETS!") and that's sort of a silly reason to not like 8C if you've really got to pick one. (Rushed, uneven art; fantastic middle that doesn't build to an equally emotional payoff; there's more.) Anyone can argue back and forth as to what was going on in that end fight, make up their own No Prize explanations for their side of the argument.
For me, the real meat of the DCU is in OYL and 52, just totally free to let loose with the Morrisonian Strangeness and Silver Age Craziness. What was that villain at the end of Up, Up, And Away? The Kryptococchus? That's the kind of ish I'm talking about.
I'll admit a fondness for Civil War these days as well, even though Front Line's "Political" "Allegoricalism" at the end of every issue is borderline offensive ("Oh YAH, Japanese Internment Camps were totally JUST LIKE Spidey's Crisis Of Faith!") The series itself is tight and engaging in all the ways that House Of M was languid and uninspired. Mike Carey is actually writing an X-Book that's worth Bachalo's time again. I can sit though Uncanny these days, even though Brubes has kind of lost me on Cap and I'm kind of "just reading" Daredevil the way I just watched a Sorkinless West Wing.
For those of you like it on the other side of the tracks, here's my book of the month:
One Half Comics As Lit Treatise, One Half 60's French Cinema Heist Caper. Really Fantasgreat.
