At first, I didn't like it. It was nothing like I imagined. It took the main character, Jesse Mastriani, and placed her in a just-after-college setting. And she was nothing like I imagined, which can be quite annoying when a book goes TV or movie on you. But! I've grown to like the characters as themselves, and not just as I saw them once upon a time, and I'm now almost finished with the 2nd season.
Now comes the part about quirky characters. My favorite character happens to be their
supervisor, Assistant director John Pollock. At first, he came over as cocky and selfish. And he is that. His image in the force means a lot to him. He's stubborn and rude, intimidating and demanding. On top of that, he takes a lot of the credit for himself. But, he is amazingly smart: he has some tidbit to say on any and all subjects, and he finds ways to OK things he knows are right, without actually letting down his guard and seeming all warm and cuddly. I like that. He's really grown on me as a character. Witty, smart, tough. He's kind of a jerk, but that's part of his style.
If you want to check out the show, it's called Missing, based on the books by Meg Cabot writing as Jenny Carol - the 1-800-Where-R-You series.
