DC Comics' universal relaunch, the New 52, has been very successful. It allows a lot of people to jump in to comics that they either have had no exposure to, or perhaps some peripheral exposure. A couple lines of books remain untouched, for the most part. The Batman and Green Lantern titles still have a lot of the same themes running through the new books that were present prior to the relaunch.
Light spoilers ahead.
Hal Jordan is no longer a Green Lantern, but Sinestro is. In fact, these first six issues are just as much about Sinestro as they are about Hal Jordan, if not more so. In a nutshell, Sinestro doesn't want to be Green Lantern, but uses the opportunity to save his home planet of Korugar from his own Corps, the Sinestro Corps. It turns out our friends in yellow have decided to enslave Korugar, and Sinestro will have none of that action.
He enlists the help of Hal Jordan, who the Guardians kicked out of the Green Lantern Corps. Sinestro creates a ring for Hal, but the kicker is that Sinestro controls Hal's ring. Lots of arguing between the two, double-crosses, and some pretty cool moments for each throughout. The Guardians have a plan to replace the Green Lantern Corps, and will kill anyone who gets in their way. What? I am not sure where this is all headed in regards to resolution, but I just want Hal to be back in the driver's seat.
I have not yet read GLC, Red Lanterns, or The New Guardians, but from what I have heard, Red Lanterns is a little iffy. We'll see! It's tough to read some of the stuff out there in regards to comic reviews because they are always so inherently negative. I swear sometimes some comic fans truly are not happy unless they are bitching about something.
Buck up, little campers! Enjoy the ride!
