Here is a review from Zap2It.com:
Out of all the dramas presented by CBS, this is the one we find most intriguing. Today's cop show tends to focus on the workplace, only giving us glimpses of our characters' families when they're relevant to the case. "Blue Bloods," however, seeks to show viewers the police force through the unique perspective of a multi-generational family of dedicated NYPD officers. Tom Selleck is as compelling as ever in the glimpse we got, but we couldn't help but focus on Donnie Wahlberg's character, a detective, and Selleck's son. Wahlberg's character was unapologetically violent, to the point where we wanted to turn our heads as he smashed a perp's face into a toilet seat. This is definitely where it belongs in the Friday night 10 p.m. timeslot. We'll definitely be tuning into this one, because while the brutality makes us squeamish, we're interested to see if it can maintain a balance between a character-driven show and a typical cop procedural.
