Fans of the CBS cop drama Blue Bloods have noticed inconsistencies in the portrayal of Erin Reagan's ex-husband, Jack Boyle. While the Reagan family has always expressed animosity towards Jack, his actions on the show do not always align with his reputation. Viewers are frustrated with the character's inconsistencies and are unsure whether to love or loathe him. Actor Peter Hermann's busy schedule, including his role on the show Younger, has limited his availability to appear on Blue Bloods. However, there is a likelihood that Jack Boyle will continue to make appearances on the show.
