I had this in a standing order due to a crossover with Doom Patrol but I have quite a soft spot for Zatanna whose costume is a crazy mash up of formal stage magician and dancer.
This is a world event storyline and I've not read anything else, apparently most of the world have fallen asleep and are trapped in their nightmares. For Zatanna these fears manifest as her dead petty criminal father being mean to her. While the script was a bit leaden I actually liked the way the interior dialogue explored the ambiguous nature of bad parenting and a child's need for approval.
I liked David Baldeon's art and cartoon style take on Zatanna but the antagonists were a bit generic, although the lack of character in them isn't exclusively the artist's problem.
Ultimately there's no consequences in the story as it just get's us from A to B in a crossover story but it was more charming than annoying along the way.
