I'm checking out Brian Michael Bendis's run of Guardians of the Galaxy from the Marvel Now line, and it's actually pretty good. I've seen a few things people mention him being good with.
So why is Civil War II written so poorly? I don't just mean the deaths now; I went into #1 to read some and between the poor dialogue (oh yeah oh yeah oh yeah), the poor characterization (Tony Stark and Carol Danvers, recovering alcoholics who joke about drinks tonight--classy!), and hand-waving current events of the Marvel universe (mutants are dying because of the Inhumans, but the X-Men are fine hanging out with Medusa and crew because "it's a party"), it's a shit show.
My guess, and what I'm gleaning from other Bendis stuff, is that he doesn't care. When he gives a shit, it shows, and when he doesn't, it also shows. While ALL of these properties exist to make money--even Marvel's push for the Inhumans, regardless of actual sales, is to prime them for the spotlight later when they hope to reap the profits--there's a difference between a money-maker story where the writer has a story to tell and one where it is just the money, not the soul of it, and Civil War II #1 reads like exactly what it is, a corporate decision. Everyone's a chess piece, and there are kings and queens, knights and pawns. Doesn't matter who they are as a character, just that character's connections and role. Tony blames Carol for Rhodey's death because each is the leader of a pre-determined side, despite how obvious a threat like Thanos would be for the use of the future sight power. No one listens to Tony that they shouldn't be so quick to trust Ulysses because if they did, the conflict wouldn't so immediately lead to the Inhumans storming Stark Tower later this month. And so on.
So, I won't write Bendis off entirely, which is what I thought I'd be doing after reading this dreck. But I will be careful, especially since the Marvel Now run of Guardians doesn't seem to be collected properly into trades (please correct me if I'm wrong; I'd really like to get this--the run with Venom and Kitty Pryde). (EDIT: Never mind. There was the Marvel Now run, and then the new run, but Marvel calls them both ongoing. See? This is the problem with constantly resetting to #1; it gets really difficult to figure out which volumes correspond with what you want to read since the collection numbering becomes useless.)
Maybe later on in Civil War II, Bendis will start to care and the writing will get better. Kinda doubt it, but they have seven issues of this to go, so who knows?
