I'm almost done catching up on all my Green Lantern reading and I have to say so far I am not enjoying Wrath of the First Lantern all that much. I've read up to issue 18 of all the involved titles and so far it is just "meh" to me. I enjoyed Rise of the Third Army much more.
I'll also drop Red Lanterns as soon as this storyline is done. In fact, I probably could have easily done without reading any of the Red Lantern crossover issues and still understood the story just fine. To be honest I'm not sure how Red Lanterns has made it this many issue. I picked it up up starting with issue 13 and so far none of the issues have appealed to me at all.
