Supergirl was enjoyable, but it's being an origin story gets some minus points. For someone totally new to the character this may be fine, but I know she's Kryptonian and Superman's cousin, I don't need an arc to tell me that. This may pick up, it was fun enough to get another issue or two at least.
Wonder Woman was a fun, but too short read. No fault to the writer, I just don't want to wait till next month. I like the lack of origin story, being familiar with the character, origin information can come as we go along to give background for new readers. Lots of questions of interest, creepy gods who are getting more character than toga wearing bores, and a kick ass Wonder Woman. I have been missing her ever since Rucka left the book.
