The Humans is an excellent dark comedy that sticks an alien, who hates humans, in a human mathematician’s body, and gives it several assassinations to carry out. Advanced math is unexpectedly involved.
The alien experiences the wretchedness and wonderfulness of humanity mostly via the mathematician’s family, who have no idea that their husband and father is now an immortal, nearly omniscient, and very lethal alien with murder on his mind. Hilarity ensues.
Recommendation: Absolutely read this. The first half is the best and funniest part, but the remainder is still fun, even if a little more predictable.
