Fans of "Blue Bloods" have expressed their disappointment with the show's attempts at humor, particularly Danny Reagan's corny jokes. Additionally, viewers feel that Jennifer Esposito's comedic talents were underutilized during her time on the show. Another area of contention among fans is Nicky Reagan, Erin's daughter, who has been called an unnecessary distraction from the show's main plot. Many viewers find her to be obnoxiously naive and consider her departure from the series a positive development.
