I thought this might deserve its own discussion. Why does it seem that much of post-1980's sci-fi is so bleak and humorless? I ask this as a ST:TOS fan. You could see the beginnings of this trend in ST:TNG with the characters taking themselves oh-so-seriously, but at least there was the occasional glint of humor or an appearance from Q to deflate their pomposity. Compare the new Battlestar Galactica with the original. I can enjoy something that is "dark," but there's no need to be humorless. Doctor Who has its dark and serious moments, but it's equally funny. Firefly certainly got dark, but the humor was there too. Why is it missing in some other shows? Are we seeing the work of former fanboys who were a bit too obsessed as adolescents, cringed at every comical robot or cute Ewok, and grimly vowed that if they ever made sci-fi, things would be different? Could they never lighten up? I guess humorless sci-fi must appeal to some people, but I'm not one who would keep coming back for that. "Realism" is just fine, even "grittiness" (whatever that really is), but with no levity it's not even realistic because humor is part of human nature.
