Science fiction has an unfortunate habit... it likes to put humanity on a pedestal. Somehow, we're just this awesomely wonderful race. Special and wonderful and just lovely. What does it mean?

Basically - humanity isn't much. People think that humanity is the greatest thing ever. Destined to heal the universe, ascend to a higher plane and so and so forth. Even Babylon 5 thought that humans were pretty amazing... despite our lack of comparative technological advancement. Not that it really spelt out all that much.

Unlike Star Trek - which went "Oh by the way, Humans are pretty much awesome and will become omnipotent!" and SG-1, which said "Humans are descended from omnipotent beings!" Hell, Star Trek had the stupidest episode ever where an act of immense stupidity - wilful exposure to a deadly virus - was expounded to make humans somehow special... especially stupid, I'd say.

Farscape was better. It liked to point out that humanity was - of the species shown - the shortest lived, the least resilient... just generally not that great. Which is somewhat ironic given the fact that 99% of races in Star Trek lived easily twice as long as Humans. Men in Black also playfully poked fun.

Dr. Who seems to be uncertain - at times, The Doctor is keen on humanity. Lauding humanity for going off and exploring, then going off about how humanity are "the monsters"... Still, given the focus of the show - especially as it is now - he pretty much has to be enamoured with humans... or the show wouldn't work.

Also, human morality - that is to say Judeo-Christian flag waving, truth, justice and the American Way morality - is the best in the universe and superior to all. Realism isn't an object, eh?
