Notably the death of Alex Luthor. Him getting fucked up and murked by the Joker after he didn't let Joker "play" was quite poetic. Plus Superboy Prime carving the "S" into his own chest while in the Green Lantern's prison was suitably creepy too.

IC started to fall off after Superboy went ape-shit and killed all the extra Teen Titans/Outsiders, but up until then, it was doing pretty good.
