Hmmm, Contact came out the same time as Gattaca. So I guess it is a draw as to which was the last good SF film.
Pitch Black, although not the best SF film, does harken to the good old fashioned "Sci-fi" B-movie years. Well, at least it didn't have giant robots! Ditto can be said for Event Horizon - not the greatest, but hot damn, the whole movie gave me fond memories of playing Doom in a dark room.
It looks like the only media that still has strong SF support would be in the area of computer games. Homeworld, Half-Life, Doom, Halo (the novels aren't bad, all things considered), Master of Orion, Total Annihilation, etc. are clearly SF-oriented and extremely popular.
Well ok, they are tuned toward mega-violence - too bad there aren't more SF games like LucasArt's "The Dig", which is one of the few non-violent SF games out there.
Anyways, as to print fiction: it still irks me that Harry Potter and the Order of the Phoenix won the Hugo. Yes, it's a very good book, but where the hell is the SF? I don't know the history of the Hugo awards, but I always had the impression it was about SF. Sure, there is a more broad genre called "speculative" fiction, but anything with magic is still fantasy in my book.
But not all is bleak: After attending a recent local Fantasy/SF convention, it seems that the male/female ratio is perfectly balanced now. There seem to be as many female writers as male writers, although a large majority of the female writers work in the fantasy genre. I'm thinking part of the decline may be that women just aren't interested in SF at all. But this isn't very surprising, considering that the situation isn't that great in academia either.
Still, things may be improving, albeit slowly. I'm hoping that the surge in popularity of Babylon 5 will spur things along again...
