Darth Acheron
I've read alot of the posts and I'd say I agree with a lot of them. The old Nick shows would be great. Here are mine:
Heroes (it ended weird)
The Cape (Also ended making no sense whatsoever)
The Event
Terra Nova
The Cape was doomed to be cancelled from the beginning, it tried to replace Heroes and was way too cheesy with the superhero genre. Lets be happy they cancelled it before the storylines started making even less sense.
