I just finished JLA Volume 1 by Grant Morrison. Overall, very creative stories. My one complaint is that he always rushes the ending. He would spend a long time really hyping up what's happening, then finish it off quickly and with no effort but this is a small complaint.
Electric blue Superman makes an appearance in this 90s comic. I don't know what graphic novel covers the electric blue Superman story but am looking to find out.
Overall Great stories.
