2001: A Space Odyssey... now there's a boring film, no wonder the monkeys were killing each other. I thought the music from that was Vivaldi or Gustav Holst.
If you ask me, John Williams will be classed as a genius to future generations. Not very 'arty farty' but his music always seems to make a difference to a film - gives it that air of urgency, magic, gentleness and wonder.
