In the movie theaters you see people on the edge of their seats. You see people trying to figure out the movie themselves instead of just sitting back and relaxing during a love story. The same thing happens with reading books. I think all people of different ages like mysteries. It gets them thinking, and has them trying to solve a problem.
Mystery movies are good because they are suspenseful.
People feel like they are put into a real live situation where they are the detective, and they have to figure out the problem. They like to finish the puzzle themselves. I also think that people like to be freaked out and baffled by the mystery. Mystery stories are so much different than love stories and adventure stories. What makes mystery stories so different from other genres, is the way that the problem is solved.
