Man, B.K.Vaughan came back to comics with a vengeance. He still might get Lost Under the Dome, where he seems intent on creating the worst TV show he can, but he's proven that when it comes to comics, he can still come up with ideas that are unique and exciting. 
 Exactly. Yes. 
 What bothered me a little about 'Y: the Last Man' and to a lesser extent, 'Ex Machina' (before he departed for a career in TV), was his propensity for writing cheesy dialogue that didn't quite ring true. He's maturing as a writer, and obviously still having fun indulging his love of SF and Fantasy, exploring new territory and forging great new concepts while he's at it. 
 Despite the obvious Rome-O and Julie-T-with-a-baby-comparisons, the seriously twisted secondary characters -- the giant spider-assassin with tits, the fucking Monitor-Heads who can't seem to keep their Id from projecting disturbing images across their screens, the floating ghost-child babysitter with her guts hanging out -- these are the kind of details that'll keep readers engaged, along with all the larger, obvious questions that need to be answered. 
 The artwork by Fiona Staples is incredible, as always; her work on North 40 drew me into that series, but unfortunately, the writing wasn't worthy of her prodigious talents. This time, it is, and I'm glad that she's working on a creator-owned series that will make her as sought-after an artist as Frank Quitely or Eduardo Risso. For now, it looks like she's got her hands full with Saga.
