My wife and I were immediately captivated by the show, and it became "must see TV" for us, as in fact it turned out it had become for several other couples we ended up hanging out with as the first season continued.
Still, for many, Scully and Mulder remain as two of the most memorable characters ever created for a television series, and the overall spookiness of the show has created a seemingly deathless fanbase that is no doubt waiting with bated breath for the series' much anticipated (supposed short form) reboot.
The reason why that aforementioned question about remembering where you were when you first saw The X-Files might not be so very ridiculous after all is that the show, in fact much like Lost several years later, was something rather unique and previously unseen, though creator Chris Carter has always been quick to point out antecedents like his childhood favorite Kolchak: The Night Stalker or (at least tangentially) anthology outings like The Twilight Zone: The Complete Series .
But from virtually the get go, The X-Files managed to offer a decidedly different take on the paranormal, one anchored in the personal travails of FBI Agent Fox Mulder, who has been dealing with the mysterious disappearance of his kid sister years ago, a vanishing Mulder has ascribed to pesky alien interloping (and abduction).
When Dana Scully is appointed as his partner, in part to putatively debunk his "X-File" investigations into enigmatic happenings that have no obvious rational explanation, the stage is set for an "odd couple" pairing that features both a "believer" (i.e., Mulder) and a "skeptic" (i.e., Scully).
Two FBI agents, Fox Mulder the believer and Dana Scully the skeptic, investigate the strange and unexplained while hidden forces work to impede their efforts.
