The X-Files resonated with viewers so well that it lasted ten seasons, and then spawned two movies and came back as a mini-series.
Even the simple premise of having one partner who believes in the supernatural, and one who believes in science, it gave us a nice balance of views between the two. The show also had some gnarly monsters, some cool ideas, and some downright creepy moments.
Therefore, it was hard to select the best episodes from all ten seasons, but the attempt was made the rank the top five episodes of The X-Files at TVOM. See if your favorite is in there. There are video clips for each.
