Wow - GREAT thread! I didn't know so many people loved this show! I only own season 6 (most of my favorite episodes, Dreamland Pt I, II, How the Ghosts Stole Christmas, Triangle, Drive, Rain King, Arcadia...) and that's merely because Best Buy had them on sale for 49.99 instead of 99.99.
I got sucked into the 1st season, I was like, 8 or 9 I think. So great. Scared the crap out of me, some of the episodes (the ones with the ghost that crushed people's necks from the inside out, for example).
I used to militantly watch X-Files when it was on Friday nights... Then that 'Millennium" show came on, and bumped it to Sunday night... Grumble...
Plus, my name is Samantha, so I always thought it was cool that that was his sister's name too... WooOo!
I even made my parents take my pre-teen self to an X-Files convention way back when (first couple of seasons), and am mad I wasn't quite interested enough in the guests -- The Lone Gunmen. (ARGH!).
When I was first in line for the movie, I was happy to see theatre employees dressed up as FBI agents... I enjoyed the SciFi vendors seeling X-Files wares (I think I have wo aliens wearing I love Mulder/Scully shirts) and a recreation of Scully's badge.
I even contemplated cutting my hair to look similar to hers... I always liked her styled bob.. (Ahh!)
I was a member of the fan club, I wore my 'The Truth Is Out There' shirt proudly, despite being too large for myself... I still have my 'Deny Everything' sticker on my window and I even have the 'I Want To Believe' Poster from Mulder's office. I thinkI still have the X-Files hat I have, and some of the trading cards and a few of the books.
That being said, I hated, hated, HATED, the seasons where Mulder was gone - and I kind of zoned out during seasons 8 and 9. I managed to catch the last episode on mute (a friend of mine called, and now I've yet to actually see it), and I've been catching the re-runs on TNT way late at night and burst out laughing at the sheer un-X-Files-ness of the episodes with Doggett and them all... Not good at all.
