Jonathan Hickman is making some really great comics. Manhattan Projects is one of these great comics. Hickman's writing is what happens when Warren Ellis gets over the fact that mainstream comics are littered with men in tights and plays nice with us.
Manhattan Projects is about mad, evil scientists masquerading as protagonists in post-WWII America, crafting abomination after abomination in an underground bunker and the redneck American cum Army General who commands them all to do it. Hare-brained ideas are strewn throughout this book.
Granted it may be due to the era that Hickman choose, but it is nice to see some fantasy revisionist science fiction that isn't riding the steam-punk wave. It is pretty much near perfect, Manhattan Projects is.
