Jesse Stone: Thin Ice broke a couple of franchise traditions – and ended on the bleakest note of the entire series. Thin Ice is the fifth entry in the Jesse Stone movie series, which adapted the Robert B. Parker novels of the same name. Parker gave Selleck two rules to follow while adapting Jesse Stone; one, Stone will always be hung up about his ex-wife Jenn, and two, he will always have a problem with drink (via TV Insider). This formula keeps the character trapped in a toxic loop, but Thin Ice needed to mix things up after four movies.
