My fiancee (who always watched the X-Files) and I (who never watched it) went to see the movie Friday night. I thought it was pretty good and I liked that I didn't have to know any background the series to enjoy it. I thought it was suspenseful and entertaining.
I was really happy to see some closure to some of the storylines that were still open when the show went off the air. I miss seeing the girls, but I watch the reruns all the time. I was very happy with this movie.
