why Pirates of the Caribbean makes people want to watch?

In this movie, the story is between set in 19Th century and 18 century. In that time, Caribbean has a lot of Pirates and many different mystical things. In the world history, i do not think it has too many point can like 19Th century and 18 century has many mystical can use. So the author of this story did really good job of take a good point of history. Otherwise, the author put action, adventure, comedy, fantasy, romance... and 'politics' that only show on third one in. politics is very hard to make it put in the story, and let it show on the action movie, especially in the action movie. Because most of action movie even they have politics in the story, but those kind of nothing in the movie. For example, in Rambo, whatever government decide to do, after that all turn to be Rambo personal massacring plan that make politics become nothing in the movie. However, Pirates of the Caribbea have an other reason makes it interesting that they choose right actor be their. For example, they use Orlando Bloom be their main character that make lot of girls went to watch the movie because of him. Those are why it can makes people want to see this movie again and again.
