As Blue Bloods enters its 13th season, the question of how long the show can continue arises. The drama has followed the Reagan family since 2010 and has a formulaic element to it. Tom Selleck, who plays police commissioner Frank Reagan, expressed his willingness to continue until Season 15. Ending the series at that point would allow for the characters to settle into their next chapters. However, the show would not be the same without Selleck, and continuing without him may not feel right. Ultimately, the decision on how long Blue Bloods should continue rests with the viewers.
