You do realize Firefly was canceled without even finishing its first season?

It was canceled, but it's not dead. It's only being distracted by something shiny... it shall return ;-P
After all, the 'verse can only handle so much awesomeness + beauty at a time. Give it a little longer, then it'll be ready to go again!

Ps. Fox royally screwed up by airing the episodes out of order... so sad. SG:U can't use that as an excuse. Alas, it had such potential, but it turned into a boring space soap opera to me... and I'm a BIG Stargate fan that wanted more realism

PPs. Heaven is made up of angels that are clones of Kaylee! <3
