Star Wars, Episode 3 revolves around a passionate love gone wrong. Anakin Skywalker has built up insecurities on what he feels others in the Jedi council believe him to be and grows more and more anger as they do not grant him a Jedi. Aside from his anger towards the councils decision, he holds many hurt feelings from finding out about the kidnap and death of his mother. After many visions in his dreams, he decides finding his mother but it was too late to save her. After both of these failures, he fears deeply to lose the love of his life, Padme Amidala, while she gives birth. As he continues to have visions of Padme in pain while giving birth, he is determined to growing more power to save her from death. Being in an emotional, vulnerable state, Palpatine (secretly Darth Sidious at the time) takes advantage to telling Anakin there is a way to save Padme, through the dark side of power. In the end, he joins the dark side, and Padme ultimately does not make it through childbirth. Anakin becomes Darth Vader, and the light side of the force and Jedi go into hiding, while Darth Vader and Sidious begin taking over the galaxy.
This movie is very detail and story oriented and thus would appeal more towards an audience of teenagers and older. These are based on books so there is a lot of information to keep up with chronologically. A Sci-fi fan audience would enjoy the Star Wars trilogies overall.
