I'm glad someone is apologizing to Oz! He says they aren't the first to bring war to Tibet, but that doesn't mean it doesn't matter. Buffy and co have to fight the fight, but they always have left a lot of collateral damage in their wake, and I like that that's being acknowledged for once. The poignant moment of the soldier dying was another nod to the cost of war.
Buffy having a thing for Xander does seem a bit "dog in the manger," just interested because he's with someone else. I laughed at all the "cradle robber" or "Humbert Humbert" discussion, because it is a bit true. But I think the real issue is that, while we know Dawn is now in college, I still envision her (and all of them, really) as how they were in BtVS S7. Thus, I still see Dawn as a kid, and especially because she hasn't been that active a character here, but still mostly the little sister along for the ride, as usual.
The goddesses can crush people with their hands, but they can't get out of a hole in the ground? Well, they served their purpose for the story, which has clearly lost interest in them.
One of the things that's bothering me most about the comics is that there's a lot of teasing of future plots, just giving you a taste without telling things. It's a too-obvious lure to get people to buy the next issue, and makes for a dissatisfying story. Fortunately, I don't have to wait a month for the next part! I marvel at the patience of original readers.
