Spooky, tense, Gripping
Early episodes did really well in taking old urban myths and conspiracy theories along with some new ideas and making them into really gripping TV. The interplay between Mulder and Scully was riviting and at the start the over-reaching conspiracy episodes added to a mystery and mythos. It was also very accessable and as one of the geeks in school it was strange to actually be discussing things I normally discussed with a small cadre of people with larger numbers of "normal" people.
It was reccomended, missed the pilot and caught the second episode and was drawn in. It at first actaully made me a bit of a conspiracy theorist and in fact probably due to the things I looked into made me question the more absurd ones more. You could say it had great effect in making me the cynic I am today.
