It was mediocre, B- territory. Which wasn't bad, but not quite up to Whedon's pedigree, or at least from what I hear. Frankly he hasn't produced a Marvel comic story as worthy of his pedigree yet. He excels at telling generic stories with good moments and teaming with the slowest artists in creation. Unless it is BUFFY, where he uses things like "fill-in talent" and doesn't cry a river about it. But maybe that is because he probably has more editorial control over BUFFY. Although I've yet to meet a Marvel editor who wasn't a slave to being Hollywood star-struck and would let any writer from any movie or TV show do whatever they want with any franchise or talent decision, but whatever, I'm not in the mood for another BrianWilly fight. The lateness wasn't his fault at all, he's just very unlucky with getting slow artists.
I can sense his fanboyism, but he allowed the worst bits of it to consume him on RUNAWAYS, loading it with characters I couldn't given two ****'s about and now saddling the team with another member who is literally a one joke pony. Saddling the next creative team with another new team member who has virtually no personality beyond, "I come from 100 years ago and I am experiencing culture shock" is borderline arrogant (because, of course, there is NO WAY Terry Moore would dump the new Mary Sue if the almighty Joss Whedon blessed it with life, and if Whedon seriously doesn't know the effect that his clout has on other writers, then he's the dumbest man on the face of the earth). By two arcs, that persona will be expended of all potential and whoever is still on the book will be wondering what to do with 1908 Plant Girl. But I won't care, because I won't be on the book anymore. At least when Dan Slott creates a character, he doesn't immediately abandon ship and leave the next crew to sort it out. And at least Whedon's creations in AXM like Agent Brand were fleshed more (even if Agent Brand is simply, "Maria Hill as an alien", but whatever, she redeemed herself by the end).
Maybe I'm a tad bitter because Whedon came in on Vaughan's book after Vaughan wrote it for about 4 years, had Vaughan and every other creator licking his rear, and has produced a standard action story that is not terrible but is worse than most of Vaughan's run that got more attention and sales simply because Whedon is an A-List name who wrote BUFFY, ANGEL and FIREFLY in TV and film. Maybe the sheer shallowness of the industry and the fans gets to me, and that is part of why Whedon often gets the brunt of my anger. And I hate that it was his run on his watch that turned me off on a franchise I used to love despite his attempt to do well with it, improve on his pace from AXM, and do as much with the issues he had as he could.
