Last year, Netflix completely removed "The X-Files" from the streaming service, and if you've been down about not being able to binge the series, you'll be happy to learn that Amazon Prime has nabbed the streaming rights.
Though, Seasons 10 and 11 are only available to be digitally rented/purchased through Amazon.
"The X-Files" ran from September 10th, 1993 to May 19th, 2002 (the first nine seasons), and was rebooted in January 2016 for the last two seasons.
