I have ALWAYS liked Tom Selleck. My smart assed mooching cat is named Thomas Sullivan Magnum...
His movies are great. I keep meaning to look up and order "The Slow Road to China".
I regularly watch "Quigley Down Under" and "The Sacketts".
When he started playing Jesse Stone in the Robert B. Parker based movies, it took me a while to say goodbye to the grin, the swagger, and the lightness.
That said, I Love all those films and fervently hope he produces another one.
I immediately started watching Blue Bloods. To me though it took him a whole season to not be Jesse Stone IMHO.
During that time it gave me time to really get into the kids, the kids' kids and the dad. So once Selleck become more animated in season two the show just settled down into Damned Fine Television.
I am also a big fan of Donnie Wahlberg. (though not of NKOTB...)
