Do you like Star Wars?
If the answer is "yes": this person is cool.
If the answer is "it's okay": it's likely that this person is lying, but since they won't insult Star Wars, they're okay, they just might be liars.
If the answer is "I've never seen it": this person has been deprived of a great movie. There's still hope. Have pity on this person.
If the answer is "no": this person isn't so cool, but this is just a quick way to judge people. There are other things in this world besides Star Wars, (Indiana Jones, for example).
