When I see NBC I don't watch the first season until I know there will be a second. I'll just delete Debris like I have done with the rest of their cancels. ABC seems to have the same problem.

NBC is known for that. They cancelled Las Vegas in Season 5 and never showed the final 4 episodes and left thousands of people angry. The last episode that showed left you hanging. One of the main characters was about to miscarriage and we never found out what happened.
