Season 3 of the cop-family show "Blue Bloods" is on DVD this week, anticipating the show's return to CBS's Friday night lineup on Sept. 27.

This is one of our favorite shows; my wife and I look forward to each episode as New York Police commissioner Frank Reagan (Tom Selleck) oversees Manhattan's crime-busters, including his sons Danny (Donnie Wahlberg), a homicide detective, and Jamie (Will Estes), a uniformed street cop. Then there's their sister Erin (Bridget Moynahan), an assistant district attorney, and Henry (Len Cariou), Frank's father, the retired former commissioner.

There are also excellent supporting players, though I miss Jennifer Esposito, who played Danny's partner and left the series midway through Season 3 under controversial backstage circumstances.

What makes "Blue Bloods" better than most police procedurals is the family dynamic. This is a tight-knit group, committed Catholics that spend Sundays together, going to church and then having a family gathering for dinner, where they pray over the food and discuss whatever's going on in the script that week.

This may sound like a trite element that could become redundant and tiresome after a while, but it's inserted in a clever way each week and is always illuminating, adding to rather than detracting from the development of the characters and the episode's various plotlines.

It's good to have any show on television that celebrates family unity and devotion but it really helps that this show is so darn good.

If you haven't tried it yet, check out the first three seasons on Netflix. You won't be sorry.
