I'll start with the comparison right off the bat. I liked Marvel Divas a lot. There were some aspects I didn't love, like a sort of dumb name, and sort of misleading cheesecake covers on a book with sensibly drawn ladies done in a light, slightly quirky style. The story was centered around sort of soap opera standard plot points, but that wasn't a negative to me. I liked Divas because it was humanizing. I thought it presented at least a somewhat 'realistic' take on a group of likable female heroes that came across as having a more or less genuine sort of friendship and personal interaction with one another.
Divas was written by Roberto Aguirre-Sacasa and drawn by Tonci Zonjic. Heralds is written by Kathryn Immonen with art by Tonci Zonjic and several others. One huge difference, and I appreciate it a lot, is that Heralds has absolutely beautiful cover work by Jelena Djurdjevic. These are very nice covers and none of them is in the realm of cheesecake. Women are shown with the figures they have in the comics, but none of them are relegated to sex kitten poses.
I already mentioned the second major piece of this. It's written by Kathryn Immonen. Nothing off of Aguirre-Sacasa, but this is an excellent comics writer paired with an excellent cover artist, and what's this... they're both women. I love the writing in this. I think the characters come across as real, and it isn't bogged down on any one emotion or mood. There is a great deal of playfulness and humor in this as well as action and emotion. That to me is a formula anyone should be able to appreciate.
The story starts with a group of Marvel ladies in vegas to help Emma Frost celebrate her birthday (This was orchestrated by Scott for her). It isn't long before the crew is fighting clones released from a S.W.O.R.D. facility and the story gets rolling from there. It isn't my intention to give away much here, other than what a cool thing this series was. I don't really care where it fits into the grand scheme of things, but I would love to see more like this. It has gotten me thinking a lot about how super heroes act in comics vs how real people act, with regard to their interactions and motivations, etc. I don't have a lot to say about it yet, but it does have me thinking.
I love the art in this, but it is a bit inconsistent. I am not sure exactly what role each of the artists had, or if the number of artists had anything to do with this feeling for me. There are also some places where it becomes difficult to tell some of the characters apart. It wasn't major, but I did get a little turned around a few times. I am also not sure if all of these people would be hanging around, but it works, and I think it's justified well enough.
If you haven't checked this out, and aren't put off by good comics, or books that feature women as strong and diverse characters, I recommend it.
