The trick to managing your HBO subscription is to lock your wife in a closet and cancel HBO. In a few months, when you let her out to binge watch the full 2nd season of Big Little Lies, she’ll love you for it! … or maybe not
FWIW my wife agreed to cancel HBO now and resubscribe for a month later this summer/fall, to binge watch Big Little Lies, catch up on other HBO series, new movies, etc.. This didn’t require bondage, closets, etc. because after several years of streaming, we now greatly prefer to binge watch a season over a few evenings rather than wait for week to week episodes. That's why we prefer Amazon Prime's method of releasing the full season of their "originals". Of course as Prime members we have already paid-up-front, so they don't need to "string us along".
