They should've played with that in the reboot, maybe even the second movie. Mulder is one of a ten thousand conspiracy theorists on the internet, babbling about something called "purity control" hidden in a vaccine during a flu plandemic in 2009 and that's why the alien invasion didn't happen in 2012, but this time he's really on to something big. Another wave of alien invaders, the government is testing more secret technology, corporations are doing 24/7 surveillance and psyops, a black magic/sexual blackmail cult is taking over the country, maybe all of the above. With the internet, Mulder now has more reach than he ever dreamed possible when he was an FBI agent. But no one cares. Not even the aliens, the government, the corporations, or the cults are trying to stop him any more. How do you fight the future when everyone's okay with events that are currently unfolding? I can't think of a satisfying ending for this. Our complacency has doomed us.
