Trigonometry is the branch of mathematics that looks at the relationships of the three sides of a triangle. I stumbled across this miniseries on a streaming catch-up channel. I was intrigued by the blurb, so I began to binge-watch the 8 episodes in 3 sessions over three days. The plot was presented simply enough, but not tediously, so that even someone touched with autism like me could grasp the complexities of the human relationships presented and watching it in a compressed time period as I did allowed me to keep track of the characters despite my tendency to face-blindness. The characters are likable, but not just gratuitous. Their interconnections with each other, with family and with others had plenty to keep me involved, The occasional technique of repeating the same scene but from a different viewpoint was enlightening. I don't think I've been able to enjoy any comic drama about relationships more than this one. It finished open-ended like most miniseries. I will look forward to, and curse, any new series, because I will feel compelled to watch it all as it is broadcast.
