With all due respect to John Lennon, whose most famous lyric makes a cameo in the British black-comedy-drama series "Mammals," love isn't all you need.
People in loving partnerships screw around all the time, and unless they've already agreed to an open relationship, an affair exposed can mean a marriage undone. Prime Video's "Mammals" is promoted as a series that "explores" marriage and monogamy, which is not an unreasonable marketing peg, as the series tells the story of a marriage shaken by adultery. And yet for me the show's beating heart is something that goes unnamed — and for artistic reasons that's for the better – across all six languidly beautiful and methodically brutal episodes.
