I thought this book was especially heavy-handed, even when in comparison with the first two.  I didn't like that it was date stamped (set in 2030) and how every story revolved around early death or suicidal ideation.  Through a trip to the past, every depressed person miraculously found the strength to keep on living!  In comparison to the first two books in the series, the stories in here really lacked variety and a sense of urgency.

but then again, maybe I'm just cold-hearted.
