I just read the six part comic book series PLANET OF THE APES GREEN LANTERN crossover. It's a paralel universe type story but they did the crossover very well. I enjoyed this read a lot and you should find it and read it if you get the chance.
Kudo's to Barnaby Bagenda the artist of this series. I'm a huge fan of Planet of the Apes and I was fond of reading Green Lantern back in the day. I love Barnaby's style of art for this series and now it's got me searching to see what else he's done.
Oh, it's put out by BOOM! Studios so I knew it was going to be good before I started. I'm really being impressed by BOOM! since I've discovered them for myself.
