I wish DC would stop milking these franchises so heavily. I get that they make money doing it, so I can't really blame them, but it's just too much of the same thing for me to respect them for it. Sure, I'd probably be interested in stories from the various corps, but I'd be happier if it were all some kind of GL anthology book or something. Rather than having Red Lanterns, Larfleeze, and Sinestro Corps (with potentially more books in the future if these sell well), I'd be more interested in a GL anthology that had 3 short stories in each issue, and the corps featured in these stories could change as previous stories are completed.
I know anthology books don't typically do so well, but I'd definitely buy one like this. But, I guess I can't really blame DC for trying to make a bigger cash grab with more and more books from the same line.
