I would think the OP also has trouble watching something like 2001: A Space Odyssey, since it seems to be impossible for him to suspend disbelief.
I've never seen it. I did consider watching it in 2001 for the fun of it, never got around to it.
The X-Files is dated. How on earth did they manage having to suffer with those clunky cellphones and that primitive internet 20 years ago.
I don't think its dated badly. Sure technology moves on, but I can't see anyone doing a period drama set in the 90s just yet. 70s and the 80s have more worth a revisit - fashion (or lack of it!) the 90s is just between then and now.
Nothing dates quicker than the future.
