Person 1: So it's a work of fiction about a well-known brand, written on the internet by an enthusiast, republished as a bestselling book, and then made into a movie?
Person 2: yup.

[[Person 1 ponders this for a moment]]

Person 1: Yeah, "The Martian" and "Fifty Shades of Grey" are basically the same book.
Person 2: "Fifty Shades of Red"?
Person 1: Man, tell me you wouldn't read that.

{{Title text: I just came from The Martian, and I just have to say: Forget BB-8; I want a pet Sojourner! It's always been the cutest of our Mars rovers.}}
