The series finale of Amazon Prime Video's The Marvelous Mrs. Maisel was satisfying in many respects, most of all in showing the everlasting friendship between Midge and Susie, however, this left other beloved characters with less-than-clear endings, including Midge's ex-husband Joel. The Marvelous Mrs. Maisel follows Midge Maisel, a classic 1950s housewife who begins pursuing a career in comedy after her husband leaves her. The show, which began in 2017, has come to an end with its fifth and final season.
