Each movie is its own separate plot line, and they’re all independent from each other. However, like many series, the first flick probably does a better job at introducing characters than the subsequent releases. For this reason, I would recommend watching them in the order in which they were released, but it really isn’t that important. Unlike many popular movie series, Pirates of the Caribbean has not been seen much in popular culture. It’s actually kind of unusual – there are no games, books, or TV shows that branch off of the original movies. However, with that said, this series is undeniably successful.
