What they got right: A good origin that doesn't involve being driven mad by Kryptonite chunks, urges to kill her cousin, or any other origin oddities. (Now they just need to not change it every few issues, and they won't need the first one there to fix things.) The character isn't oversexualised like her DC Proper counterpart, so that's good. They even come up with an explanation for her wearing a match to Superman's costume. Kara is a fun kid, even giving us a less than accurate description of how she came to Earth that was funny. (As is Kal-El's "yeah, right" expression.) The way she drops in (see the preview) and her reaction to new powers is just comedy gold (or at least silver). At the same time, you feel sorry for her trying to adjust to school with her powers and lack of Earth culture. (Really should have stuck around a while longer, Clark.)
What they got wrong: I don't expect a major supervillain in the first issue. However, Superman makes the same error he did when Kara first appeared in a DC Comic. He kind of drops her off just after she arrived. He may have had the same reasons he did then, and I know Landry was trying to insure all focus was on Kara, but it still seems an error on his part as she tries to adjust to school, where the other 8th graders have heard of stuff we take for granted knowing. I've heard complaints about the character model for Kara, which actually works rather well for her secret identity. While I agree with others about the hair, she is only 12, so her body's not going to be as well…developed…as her older counterparts. Plus there are plenty of akward, lanky teens older than her, and I think it matches her personality rather well, mostly seen in her secret identity. But yeah, the tomboy hair seems rather Smallville-level off for her design.
Recommendation: I'm not as excited for this book as much as was after Billy Batson and the Magic of Shazam! #1, but only by a small margin. It's funny, it has heart, and I like the art style better than Billy Batson. I'm keeping a very close eye on this comic.
