I did read a fair bit of Geoff Johns' Green Lantern books from Rebirth onwards but found I kinda lost interest during the Sinestro Corps War. And that was as far as my relationship with GL in comics has gone. I keep meaning to watch more of GLTAS (I've only seen the pilot), since the DCAU stuff is always dependably good, but I just haven't found the time or motivation.
I should at least check out the Larfleeze episodes. Cause Larfleeze is totally the warthog/horse/man/whatever. I know I'm repeating myself, but this simply cannot be emphasized enough.
