Honest to God, I think Zatanna is going to benefit immensely from this show if it sticks around, because it gives her some really potent core personality traits that her character in comics and in other media could stand to benefit from. I like Zatanna a lot but, I've got to be honest, she hasn't really had a personality that pushes itself prominently based on key character traits to me. Maybe I've been missing something, but Zatanna has always been a character that you have to "get to know" versus a character that you immediately figure out.
But Zee is a character that immediately grabs you. She's flashy, she's fashionable, she's vain, she's self-centered, she's a little bit of a bitch. It's a really potent character. You can tell by how many people on /co/ have listed her as her favorite. Regular Zatanna could stand to borrow a few things from DCSHG Zatanna, because she certainly seems to have struck a chord.
