I've always liked this show - and am glad it's being repeated now on independent stations. When Angie Harmon starred on Law & Order, her character's pushiness and arrogance, her deep rasping voice and model's gait - really put me off. But on this show, the actress, playing the two lead detective, Rizzoli, has grown on me - her character is given a family background, allowed to show a variety of emotions, and Harmon has simply become a much better actress than years ago.
I really liked Sasha Alexander, who plays the other lead character, pathologist Isles, when she starred on NCIS and was very disappointed when she left the program (after its first year?). She's utterly charming, obviously bright (good as very necessary for this character!)
The plots are not ones you'll want to rewind to see how the complex pieces fell into place (this isn't Columbo) but they are involving enough to carry forward the narratives of the shows.
The supporting characters are well-enough written - though the humor is often hokey.
The warmth of the ensemble is very noticeable - one senses not only that the characters are supposed to like each other - but that the actors really do. It's a strange thing to say that a police detective show is heartwarming - yet this is.
As one comes to like the characters more and more, it's their back stories and their concurrent personal stories that make this a very welcome watch.
There's nothing BIG about the series - it's modest, light, and has its own charm and warmth. I really like it.
