Great, terrible maybe but never had a boring acid trip.
2001 was a great movie, loved the book as well.
If anything is dead it's film makers (Hollywood's) creativity. Remakes and sequels rule the day. Which of course explains the popularity of making films based on comic books - a large source of new "creative material"
Gotta agree here: loved the book and I really enjoy Kubrick's artistic vision and superb skills.
Also, you young people are demonstrating an incredible myopia for the genre; the Golden Age of SF was the fourth and fifth decades of the twentieth century, together with a "New Wave" of the sixth and seventh decades.
Don't tell me you are all ignorant of classics like Metropolis (1927), The Day the Earth Stood Still (1951), Forbidden Planet (1956), the original Invasion of the Body Snatchers (1956), The Blob (1958), etcetra, etc!
As for the death of the genre, I would say that people are being a little premature ... AND I would say that the genre was very tired after a couple of decades and needed a rest ... a bit like how Doctor Who was bankrupt after John Nathan-Turner's production career and only returned when a diehard fan, in the person of Russell T Davies, with some vision could do so after a decade and a half lying fallow.
Now there is a resurgence of SF, like the recent films of from the books of PKD (Through a Scanner Darkly (2006): the only author with more film adaptations of his work is Stephen King ... no, Ian Fleming doesn't count ;p ) and Asimov (I, Robot (2004)), to name only two; the bar is a lot higher now because the audience contains (geeks) who understand a lot more science to a higher degree.
PS Ridley Scott freely admits (in the DVD special features) that the "dirty future" of Lucas's Star Wars film was a huge influence on his vision for the Nostromo and Alien.
