The premise sounded fascinating, but the execution left me cold and uninterested. Perhaps I am entirely the wrong audience, and is better suited for newcomers to the world of manga, rather than someone who's been involved since the 90s and is no longer amused by wacky manga conventions. 
 I've followed Colleen Doran's blog for some time, and while I admire her work ethic and knowledge garnered from years of experience, I don't particularly like her attempts to play chameleon with her art style. I easily see where she appropriated stylizations from prominent manga art styles from the 90s (dated CLAMP, usually), but they are hack imitations with no inspiration, flow, or true feeling that I would have expected from an artist of her caliber. 
 A huge component of graphic media is the ability of the artwork to portray the story, and many times I've had fabulous art lift up an otherwise mediocre storyline. But poorly suited art does just as much to drag down the written word, and Mangaman is not written well enough to transcend that.
