I'm not sure how I feel about this one. the subject is exploitative so I wasn't sure if this guy, Derf, was cashing in on something - even if it is 20 years later. the drawing style reminded me strongly of a particular segment of MAD magazine. at first this made the illustrations appear trite, but when I realized the timeframe of the story (the 70's) - that was the height of MAD magazine's popularity in my household too - then the drawing felt appropriate, and belonging to this era.
as for the actual plot, the author does a decent job of keeping it at the moment. he doesn't colour much of the content with foreshadow, or what Dahmer ultimately becomes. it is supposed to humanize Jeffrey Dahmer (but I read his father's memoir decades ago so it didn't need to do that for me) but there is a truth about how you act around your buddies - the mask you put on - and it is unique from how you behave around your parents/adults. so this book actually makes for a fuller picture.
