If anyone is in the dark its this writer
I am not impressed by this title at all. The concept and starting point is there, but the character writing and art are off putting, dull, wooden, and really the characters don't quite act as they would while some of the art doesn't pay attention to the writing... In particular we have Superman talking like a robot, Wonder Woman saying things similar to what Batman would say, Cyborg just there for a punchline. Batman smiles... for some reason. When Zatanna uses a spell for binding feet it binds the entire body, and none of the characters are really introduced... and most of these characters are relatively unknown.
Xanadu's back story is in Demon Knights
Shade is from I don't know where and his origins aren't told anywhere I know of
Deadman you have to pick up DC Presents
John Constantine is a little known DC character that I have no clue about
Zatanna's backstory is not given
June Moon/Enchantress Only if you've read other things do you know they're linked otherwise June Moon is just out of place.
So we're expected to know these characters from other books so this should be a team origin story, but the story meanders and in general doesn't go anywhere or tell us anything...
Further the cast of characters and name for this book is just out of place. They should have named this something else, something like one of those magic groups I can't think of right now and/or included better characters such as Doctor Fate, Spectre, Black Alice, Misfit, Captain Marvel, Mary Marvel, Etrigan (which even though the profile says is in the book I didn't see), Traci 13, Empress, Donna Troy, Shining Knight, pick a pantheon and draw from them considering all the gods exist in DC. All of these characters would have been much better for a JLD book than the characters we do have for it (Other than Zatanna and maybe Xanadu).
These aren't bad characters mind you, just they aren't good for team books and definitely not good for a book called JUSTICE LEAGUE Dark.
