Roughly a year after CBS canceled the long-running, family-focused Blue Bloods after 14 seasons, the network is expanding the franchise with Boston Blue. Donnie Wahlberg reprises his role as hotheaded detective Danny Reagan, now joining the Boston Police Department alongside new partner Lena Silver (Sonequa Martin-Green). Danny’s son, Sean (Mika Amonsen), is also following in his father’s footsteps as a rookie cop.

While Boston Blue is its own show, it maintains the charm of Blue Bloods. Entertainment Weekly praised its “easy, buddy-cop chemistry” between Wahlberg and Martin-Green, keeping the familiar heart and family focus of its predecessor.
