OK, unless you have a Neilson box, or know someone who has, the best thing is to buy the DVD's and merchandise and send letters to the above addresses.
OK, here's a draft of mine. Let me know what you think or if I'm missing anything:
To Whom It May Concern:
This letter is in support of the animated television show "The Spectacular Spider-Man." As a longtime fan of the character since the early 70's, I say this show is absolutely the best adaptation of the comic of any animated or live action incarnation. It is a show that I can enjoy along with my children (ages nine and twelve).
Rumor has it that this show may not be picked up for a third season. This would be a poor move for what is currently the best animated show based on a Marvel Comics property. This show deserves at least a five season run. And with "Spider-Man 4" soon to be on its way to theaters, it would only make sense to have a television property along with it. And why start up a whole new show, when you already have the definitive Spider-Man cartoon that is critically acclaimed and loved by fans of Spider-Man? It would seem more cost efficient and to maintain the superior quality, for you to continue the series with the creative team of Greg Weisman, Victor Cook, and Sean Galloway, a team who obviously knows how to handle the property.
So it is my sincere hope, along with countless other fans, that this show is given the green light for future seasons. Thank you for your time.
