I am a child of the Star Wars generation. SW changed my life, and even though I have moved on from them and can see the real flaws in the Star Wars movies, I readily admit that the first SW movie (A New Hope - it is now refered to) changed my life.
Otherwise I am a big fan of TV shows Babylon 5, Blake's 7 and Firefly. Movies including Bladerunner, Excalibur and the Alien franchise.
