If you'd like to call Ted a liar, then by all means do so. Better do it to his face though, since talking behind someone's back is rude.
Apparently, Ted's belief is that the compass is pointing at Will, which I find extremely interesting. Besides, we don't know exactly where Will got off the ship (I somehow doubt he waited until the ship went underwater to get off. Probably as soon as they came in view of the island he was in the water, swimming away from the ship), so when the compass 'points' at Jack, it could actually be pointing at Will.
Also, when she's wandering around on the beach, looking for the chest, and the compass keeps swinging around, she actually heads in the direction that Will appears from before she turns back around.
The compass still worked to find the chest. She just misread what the compass said. She thought it pointed at Jack, it was actually pointing at the chest.
Sorry, guys, but nice try. Will and Elizabeth are in love, and will probably get married. If Will does end up dying (though I've seen nothing that supports that truth except a nasty magazine article that looks rather suspicious), I somehow doubt that Elizabeth is just going to fall into Jack's arms.
She has a better chance of ending up with Norrington than she does with Jack. Just because Jack and Elizabeth look nice together doesn't mean that they should or will end up together.
Everything that you point out as being a J/E moment (Oh look, the sky is blue!!!) can be easily and logically explained away. The ONLY way YOUR ship works is if Will dies or suddenly vanishes. That fact alone should tell you that your ship has more holes in it than swiss cheese.
Normally I wouldn't get this riled over J/E shipping. I can debate politely with anyone, given the opportunity. You can even call me any name that you like, but when you DARE to insult the WRITER of this film and try to pass off his opinion as LIE because it intrudes on your false little dream of a ship...That is IT.
You have absolutely NO BUSINESS calling Ted a liar just because you don't like what he said. Nor should you ever, EVER call someone's ideas crap. People are allowed to write or believe what they want about the movie, and until it comes out, you are just going to have accept it. You can debate all you want, but NOT LIKE THAT.
Got it?
