I’ve never seen a single episode of The X-Files, Star Trek: Discovery (and I’m a Star Trek fan), Stranger Things, or Game of Thrones. (The only parts of Game of Thrones I’ve seen were Cersei’s Walk of Atonement, and Joffrey’s death.)
I’ve seen the first two Lord of the Rings movies and wasn’t impressed enough with them to want to watch the third. I fell asleep in the theater in the middle of The Hobbit: The Desolation of Smaug, and remember very little about it. My landlady’s daughter’s family decided to treat us all to a day at the theater, and for me that meant being dropped into Part 2 of a trilogy I’d not seen Part 1 of.
