I still feel pain when I think about Carnivale being cancelled. It was so freaking good and it left on such a cliffhanger. Ugh. I keep hoping Netflix is gonna bring it back to life but it's been so long.
Freaks and Geeks was also great and way too short.
I also liked Terra Nova even though it was awful and I totally understand why it was cancelled. It was a guilty pleasure though, and I liked the premise a lot.
