I might go and see King Kong for the effects, but I am not going to see it for the story. I just hate Peter Jackson films. I have seen 5 films he did (LOTR trilogy, Braindead and The Frighteners), and absolutely hated all of them.
I know this will probably get me flamed (maybe not here, but it would on other sites), but I thought the LOTR films were the most boring rubbish I have ever seen, although War of the Worlds was not far behind.
To me, all of these summer blockbusters are the same - decent action and done on a really impressive scale, but have stories that wouldn't look out of place on a made for TV movie.

Just my 2p.
