* BrokenBase: This is easily the most divisive of the five novels, with some fans hailing it as an unsung classic for giving Arthur some much-needed character development and building up to a genuinely touching conclusion, and other fans accusing it of being a meandering and inconsequential book which TastesLikeDiabetes.
* TearJerker: At the end of the book, Marvin, who (thanks to time travel) is 37 times older than the universe and has had all of his body parts replaced multiple times (except for the diodes on his left sides that have been paining him ''for all his existence''), [[spoiler: dies]] .... But not before reading God's last message to his creation saying, [[spoiler: "We apologise for the inconvenience."]] ''His'' [[spoiler: last ]]words? "[[CrowningMomentOfHeartwarming I think.... I feel good about it.]]"
** The tear-jerking implication is that he only ''thinks'' he feels good about it... because he's never felt good about ''anything'' before and doesn't know how it's supposed to feel.
