AKA: We Can Definitely Handle The Truth
In the end, I don't think there was ever going to be a good ending to The X-Files, at least not going into the finale off Sunshine Days. By that point, the deck was too stacked against it, the plot too out of control and the lore too much to cobble together at the last minute to actually have a finale that holds together or ties up the series properly. The best they can really do is try to do something that the fans will like. To use a somewhat overly dramatic metaphor, the landing gear is busted, so the plane is coming down hard, the best thing you can do is try to protect the passengers.
