I too love this series, but I have a question that's actually been rattling around in my brain for a while: exactly how much are they allowed to show, in terms of violence, nudity, etc., in the various comic "ratings" (ie, T+, as newuniversal is rated).  The slaughter scene, while very cool, had a fair amount of blood and violence (the half-severed head comes to mind) that I would usually expect to see in an R-rated film, not PG-13 as i assume this is akin too.  So, yeah, I'd like some clarification on that, just out of curiosity.
But, back to the issue at hand (get it?  It's a joke.  Ha!), I really do like this series.  Not the best, but the powers are very creative.  Not just the usual "I can cause big explosions!" powers, and that adds a lot.  Very well written and somewhat cryptic, as all Ellis books seem to be.  Pretty good stuff.
