Read Green Lantern #2 today and I'm really liking Sinestro. The highlight for me would be when Sinestro lectures Hal about how he was never more then a mere superhero to the people of earth, and that he never tried to change anything or unify the planet like Sinestro did for his homeworld (that is debatable of course). And I laughed a little at how Sinestro was pretty much able to make Hal his bitch for the remainder of their partnership.
Also I was thinking of picking up Red Lantern, but since this corp had no animated counterpart I know next to nothing about them. Since Green Lantern got the "soft reboot" I was wondering if it would be worth it for me to get this title even though I don't know anything of what they've done up until this point.
