What they got right: After no new issues for a few months (right at a cliffhanger), the first arc ends on a high note. The sibling love between Billy and Mary are just warm and fuzzy enough to feel real without annoying the little boy demographic of the comic. The story is serious, but fun (take note, Earth-1). I fell in love with the characters all over again. Theo gets what's coming to him, and no bloodshed or possessed super heroines required. Everything is just right. Storywise, anyway.
What they got wrong: The art, as always, may not be to certain parties' tastes, as it's very cartoony. (In fact, some sad sacks were against the comic for mostly that reason back in issue 1, and missed out on a great comic thus far.) Cap's cape looks a bit short, but I don't mind the style at all. I was a little annoyed by the panel sizes, though. I miss the days when the artists weren't making the panels as big as possible to show off their artwork, thus leaving less room for the story, and Kunkel avoids that. However, on some pages, the panels are too small to compress too much at one time. Still, I prefer that, since it does give us more story, and I'm all about the story.
Recommendation: If personal events are forcing you to delay your comic for months on a cliffhanger, you'd better come back with a bang. Billy does so, or at least a POW. Now bring on Dr. Silvana! (The announced villain in the next arc.)
