This is one of my all-time favorite crime dramas, not for the storylines or the plot twists, but for the relationship between the two main characters - and for the personalities of the characters themselves. It's so refreshing to see a woman who can kick a** and be witty, sassy, street-smart, and fierce, but still be sweet, sensitive, loving, and funny. (Rizzoli.) And it's nice to have a geeky character (Isles) who doesn't behave like a robot! Their friendship is perfect. The writers completely eliminated the competition, occasional back-stabbing, and awkwardness that pretty much every single female t.v. friendship has and just let them be themselves. The result is a close-knit relationship full of humor, strength, and depth. The bonus - they're also pretty hilarious. And the mysteries are pretty entertaining, too.
