Once again, I disagree.
The heart is the most important aspect in the movie. It's what everyone wants, it's what influences everyone's lives in one way or another in the film.
The compass begins the journey for everyone, and it's what ends the journey.
So yes, the compass is central to the plot, but it isn't the plot itself. As much as I enjoy all the discussion about J/E vs. W/E, I just don't see that TnT spent the entire movie putting in teeny tiny clues to point to J/E.
I'm a writer myself (unpublished, but working at that. I'm almost done with my first manuscript!!) and I like to put in symbols and allude to future happenings, but I don't spend my time beating people over the head with 'hidden messages', which is basically what most people here think TnT have done.
I'll grant you that a J/E ending is somewhat possible, but I don't think it is at all likely, because everything points at Will and Elizabeth as loving each other. To me, at least. What is symbolic to J/E shippers is often interperated by me as to have a completely different meaning.
Such as the scene at the end of the movie where Elizabeth is crying. A lot of people think that Elizabeth is crying because she lost her love in Jack...but I'm more than certain that she is crying because she betrayed Will's love, she betrayed Jack's trust, and she murdered a man.
There is not enough evidence (the kiss looked more like desperation than passion to me) to support the idea that Elizabeth's one and only desire is to be with Jack. I certainly don't think she was so in love with him that she killed him to get him out of her life...Elizabeth is a much stronger woman than that, and it would only make her character weak to say such a thing. I also don't think that she is retrieving him to get something back in her life that she feels she's lost forever...
Rather, Elizabeth is going to find Jack to right the wrong she committed against him...basically, Elizabeth is going to look for redemption. I wonder if that won't be the major theme of the next film....hmmmmmm.....
