I am a big fan of Numb3rs. Honestly, after the first season I wondered how the show could continue with such a narrow premise. Six seasons later I am still entertained every week. The real great thing about the show is the depth of the plot. The dynamics of Charlie and Don Epps has been significantly augmented by the addition of many other interesting characters. Whether it's understanding their father's struggle with late life issues or the challenges of law enforcement agents to sustain real relationships, Numb3rs is so much more than just a cop show. It's about human beings trying to deal with their strengths and weaknesses.
If you want something great to watch, Numb3rs is for you. It has terrific acting, innovative scripts, great story lines, vivid characters and a unique space on television. It really does bring together all the best elements.
