Heroes Season 5/Volume 6 Brave New World

Have you ever seen Heroes? If you haven't I can tell you all you've missed a lot of things. I have seen it and thought that everything ends at Season 4.But in the end I was "disapointed" that the next season (or what I've heard) was canceled by NBC. Why would anybody do such a thing? Lack of resources? I thing maybe not. Bad ratings? Great televisions can't handle a bad rating,and I can tell that there were lot of bad ratings (maybe) because anybody didn't bothered to give them a good rating. It's easy for someone to say "I don't like it" and for those who like it,they just appreciate it without telling it or giving a feedback. Well,that's not good. I'm starting this petition and hope to get as many as signatures as I can,and I would be gladly greatful for you to share this petition. I want Heroes Season 5 to be filmed and continued (and hopefully never end), and I want to see it on television. If I can I could try to help Tim Kring or NBC with everything they need to start producing Season 5. Thank you for your time, I hope to make myself listened.
