This week's Injustice: Ground Zero is an enjoyable comic. Christopher Sebela continues to build upon and around the story of the original Injustice, with his portrayal of a Harley Quinn struggling to break free of her codependency remaining the serie's high point.
The artwork is somewhat weaker this week, with Secret Six artist Tom Derenick delivering some uncharacteristically sloppy work. There's some slight inconsistencies from panel to panel, such as how low-slung Harley's pants are and how high her underwear is riding up on her hips. Still, Derenick does draw some great expressions, such as the forced smile Harley wears in dealing with The Joker that does not match her horrified eyes at all.
