I just finished watching the first season of Firefly, which I bought on DVD. I caught like 2 episodes or maybe 1 1/2, when it was on TV, because it conflicted with something in Real Life. I like Sci-fi, but this is so mixed, I don't know if I would really call it sci fi. Its more sci-fi-western than anything.
I really liked it. I think it has excellent storytelling. The cast seems to mesh really well, and you really catch that they had a great vibe going on. Shamefully, it was cancelled by Fox. Didn't quite generate enough cash as the pathetic human pseudo-drama that is reality TV I guess.
I watch less and less TV these days. It has become so bland.
