This book was pretty awesome and I loved the illustrations! The story was pretty good too and I liked the part where all the backgrounds were given. It helped me connect to all the characters as I didn't know about half of their pasts.
The dialogues were good too and overall I think this is one of the best graphic novels that I've read in the recent years. The female characters were neither over-dramatically sexy or muscle-ly or gay. They were really awesome and bad-ass and I really liked Harley Quinn and Katana.
I loved Deadshot and Colonel Rick Flag and even Croc, but Boomerang was just... meh.. though his background story was cleverly told.
All in all, I liked this book better than any other that had Harley Quinn in it and hence, I'll be giving it an extra star.
