‘Boston Blue’: Mika Amonsen on Reading Reddit Negativity About Sean Reagan Recasting

When Mika Amonsen took over the role of Sean Reagan in the Blue Bloods spinoff, Boston Blue, he knew there would be backlash. Andrew Terraciano played Sean on Blue Bloods, with his brother, Tony Terraciano, playing Jack Reagan. The spinoff’s creators decided to recast the role for the new iteration. Amonsen tells TV Insider that he hopes Andrew Terraciano can see the respect for his performance that he puts into the character — and that he reads everything viewers say about him on Reddit.

Boston Blue stars Donnie Wahlberg, reprising his role as Danny Reagan, who has moved from New York to Boston to be close to his son, Sean, who’s now a rookie cop at the Boston Police Department. Sean became close with fellow rookie cop Jonah Silver (Marcus Scribner), who also comes from a law enforcement family. The Silver family is made up of rookie Jonah, Detective Lena Silver (Sonequa Martin-Green), BPD Superintendent Sarah Silver (Maggie Lawson), Boston District Attorney Mae Silver (Gloria Reuben), and Reverend Peters (Ernie Hudson). They’re essentially the Reagans of Boston, and they’ve taken Danny and Sean in as part of their family.
