This program is one of the few that stood the test of time. The characters made an impression on people and even when the plots became endlessly insane at time the loyal watchers still watched. Buffy is another one that not only spawned spin off series but came to a natural end rather than being killed off by ratings chasers. Perhaps this is the reason why Dr Who had been such a big hit. The fans hadn't finished with it and so they fell back in love with, even those of us who have grown up and should know better than to hide behind a sofa!
I think that these shows somewhere spark a curiosity in me, the unexplained, the why and wherefore of the world, probably things that we will never know, or if we do know it will be like the Galileo revelation. Even if discoveries are supported by a body of scientific evidence there will still be detractors and those attempting to prove they are right and the other people are wrong.
The X files though reminds me of all the times when you hear a piece of news and you get a shiver down your spine, get that odd deja vu sensation or know who is on the other end of the phone before you pick it up. I have had a few odd things happen, a few 'feelings' that I wished I had listened to before acting and it seems to me that sometimes we 'know' without knowing and that we can't explain that, yet. Truly an X-File.
