Another one season wonder??
I think this will be the same as Firefly, Tru Calling, etc. It will run for one season, it will be a very well made and amass a cult following. I also believe the show won't have the numbers to justify the budget and continue for a second season. It will forever live on dusty shelves in a dvd collection in 3 years.
Although the show may surprise us. I find this somewhat different than the 4400 I believe super powered beings on tv are having a true resurection. just like the early 80's where Mork & Mindy, Greatest American Hero, Wonder Woman, The Incredible Hulk, and even Small Wonder were some of the top television shows of that time, I believe that Heroes might stand a shot at true success. Given the popularity of Smallville, And Charmed (Curse you CW) I believe that just like the 4400 This show could outlast expectations and actually maintain a market share long enough to catch on. But this is merely speculation.
