I really could not care less about Batzarro and Bizarro Superman, they are just painful to read about. I was definitely just skimming the issues in this volume. The storyline with Skyscraper and the rest of them? Yawn.
Definitely inferior to the others... Never been a big fan of Bizarro and Batzarro, as reading their dialogue is incredibly annoying.. Hopefully this redeems itself with Volume 5 because other than this one, the rest have been great.
