I envision a group of four friends. They are standing outside a movie theater. The year is, let's say, 1991. They discuss the opportunity to see the just-released Terminator 2: Judgment Day.
The first friend says, "I loved The Terminator. This is the sequel."
The second friends says, "It's supposed to be the most expensive movie ever made."
The third friend says, "I love Arnold Schwarzenegger. I'll see anything with him in it."
The fourth friend says, "Wait, what is this movie? I haven't seen Terminator 1. Is this the same one wheer Arnold goes to Mars?"
The first friend says, "No, it's Terminator. He's a robot from the future."
The fourth friend says, "I'm already confused. The future? Did he come back in time from The Running Man?"
The second friend says, "No, it has a way huger budget and better special effects than The Running Man."
The fourth friend says, "I won't know what's going on though."
The third friend says, "It has Arnold!"
The fourth friend says, "So does this take place after Predator 2? I didn't get why Arnold wasn't in that one. Where did he go after Predator 1?"
The first three friends cannot persuade to the fourth friend why they should see Terminator 2: Judgment Day. They do not see the movie.
