Jack equal Han Solo who is running from an evil man, and has an equal fate and return.
Davey Jones equals Jabba the hut who is chasing Han Solo just like Davey is chasing Sparrow.
Will equals Luke who falls in love with a girl that he can't be with because it is not possible. Elizabeth isn't his sister but she has the hots for Sparrow thats obvious.
Elizabeth equals Leia who falls for the scoundral Han Solo or in this case Jack Sparrow.
How can you hate this movie when it is formated by a movie so beloved. I think it is just as enjoyable as ESB.
