Here is my attempt. I think I touched on everyone of Dr's points.
To whom it may concern,
My name is Richard. I am a 35 year old male and my wife is a 29 year old female living in Connecticut . We are both huge fans of the NBC show Chuck.
I am writing this letter to let you know how much we enjoy the show, Chuck. Rarely on TV can you find a show that brings spy action, comedy, drama and romance together is such a well crafted package. The writing on this show is top notch. The story lines are unique and the relationships that the show explores make you feel like you are part of their world for that delightful hour each week. I would like to especially mention the phenomenal cast. Zachary Levi (Chuck) is the hero we all hope to be. He is the everyday working man saving the world at $11 per hour. Zachary brings such a goofy charm to the role, he is a great comedic actor who brings allot of dramatic depth to his character. Yvonne Strahovski (Sarah) is such a phenomenal actress. She brings nuances to the role; her emotional scenes are some of the best on TV. The romantic chemistry between Chuck and Sarah is what really separates this show from its counter parts. Levi and Strahovski play off each other so well that you cannot do anything but smile when they are interacting. Adam Baldwin (Casey) lightens the mood with the occasional grunt or sarcastic remark that have my family and friends laughing so hard that our sides hurt. This trio of great actors plays so well off each other that in my humble opinion they are the best cast on TV.
I have watched this show live since the pilot, I am proud to say that I have not missed a single episode. I purchased season 1 on Blue ray and I re-watch the episodes after they air on NBC.com and discuss the show with other great fans like myself on various Chuck message boards including the great fan site Chucktv.net and the official Chuck message boards. I have gotten my friends and family to watch the show and now they are Chuck fans as well. Sadly, I feel our viewership is not being considered because we are not a member of the Nielsen's. I have read allot of positive reviews and press that praise the show, as one of the best on TV. This show has received critical acclaim and it should be secure for another wonderful season. However, I am concerned that there is talk that my favorite show in years might not be coming back for a much deserved third season.
I am writing the letter on behalf of my family and friends. Chuck is the best show on television, it is unique and has the best cast, however it is in the toughest timeslot in television. It is holding itís own against some pretty tough time competition. Please NBC renew Chuck for a much deserved third season. You would make this Chuck fan and the millions of others that tune in each week very happy.
