By Firefly, are you talking about the second best sci-fi show ever. Of course I’ve seen Firefly. What respectable nerd hasn’t? I totally agree with you. The show is fantastic, because it isn’t about the sci-fi. As for cancellation. It was cancelled because people are stupid. If you liked the characters of Firefly, then you should watch Babylon 5. Who was your favorite character. I like Mal.
