I rather enjoy the almost cartoon aspect of it all. Like Ron Gilbert said, its Monkey Island: The Movie. Davey Jones is simply brilliant character design, and watching the making of on how they did that is insane. I left the theater figuring they did some good makeup work for most of the closeups and then CG the beard and junk...nope, total CG 100%. Fuck Gollum, Jones is the best CGI character.
I don't know what it is. This whole mythical world they made and stuff. Cannibal Island, Jones and his whole background myth, World's End (where they will go in POTC3). Huh...thats it. I love the old myths, and getting to see them realized inside a world where they exist it just awesome.
