Haha, definitely a Thing knockoff, but I didn't mind. I love how X-Files was inspired by some great sci-fi/horror movies, and now x-files inspires the new movies. Most recently, I remember XF being mentioned as an influence in the commentary for Prometheus.
Aaah, Colony/End Game is so good. Season 4 is my favorite season of the show, and it probably is for a lot of people, so that could explain the higher price?
