That sounds impossible, but RIZZOLI & ISLES has had consistently intelligent story lines, as least so far. One might have expected this, because the show was created by Janet Tamaro, an award-winning journalist, and is based on the novels of Tess Gerritsen, who is actually a physician. All shows of this type have certain cliched characters for the central characters to play off of, and in R&I we have the wise, grizzled old detective played by Bruce McGill, and the overbearing but basically nice mom played by Lorraine Bracco. What sells this show is not the challenging mystery stories, though they are good in themselves. The main selling point is the chemistry between the two main characters. They are, quite simply, the cutest couple in the world.
