Multiple tie-in's to comic book mega-events are nothing new, but tie-in's that are actually worth your time and expand the main story are something of a rarity indeed, at least to me anyway. With Blackest Night, DC's latest collected mega-event, writer Geoff Johns creates a new Lantern Corps that is composed of deceased heroes and villains, and threaten to destroy all existence as we know it. This tie-in features issues from the main Green Lantern title which ran parallel to Blackest Night, and fleshes out much more of the main story as well. From witnessing Green Lantern villain Black Hand's disturbing admission into the Black Lantern Corps, to Hal Jordan and Barry "The Flash" Allen tangling with the resurrected Martian Manhunter, to Hal teaming up with arch-nemesis Sinestro and other various Lantern Corps, and a showdown between the posessed Spectre and a Paralax-possessed Hal; Green Lantern: Blackest Night isn't just smashing, it's essential. Doug Mahnke provides a majority of the pencil work here, and does a more than fine job in doing so as well. Since Johns brought Hal Jordan back from the dead and re-launched the Green Lantern title, he's done virtually no wrong during his run on the title, and that trend continues. After reading this, and Blackest Night, you'll be hoping that his run never comes to an end.
