Second season is more "hip-and-gloss" with less convincing characters and more vague approaches to crime-solving. It's ok viewing once, but season one is worth viewing again. I don't think I will try season three.
My son and I are in love with this series! Wonderful characters, and lots of human interest and police/forensics to the plot line, with just a dash of how math saves the day. Explanations are short and sweet and don’t bog down the plot. So glad we found this series!!
