Wow. Wowie Wow. I definitely need to pick up the rest of the Tom Strong trades, if this is what's coming at the end. I love how it ties in so well with Promethea, given that during his last appearance in that story, Tom and America's Best just disappear.
As for the Klock book, I think part of the issue is that it's Moore writing this. After you've written something like V for Vendetta, or Watchmen, the latter of which everyone loves to analyze and break down, people are going to be looking in all your work for some hidden undercurrent or some secret meaning, and aside from Promethea, where Moore was voicing his thoughts on religious beliefs, largely his own, there was none of that in the ABC line. It was just a guy having fun with different superhero archetypes, and getting some good friends/great artists to work with him on them.
Top Ten's just a classic take on the traditional team book, wrapped around the idea of a police force, and Tom Strong was Moore playing with sci-fi and pulp archetypes, and he did it wonderfully, even inviting people to play in his sandbox. Like someone said above, sometimes something is exactly what it looks like. And I don't think Moore intended any hidden messages in this at all, he just wanted to have fun.
