Finally went to Pirates of the Caribbean 3 last night.
I agree the special effects were incredible, but I was fairly disappointed with the rest.
I really liked the first 2 especially the way the characters interacted. In the 3rd, they seamed to say the heck with it, we will just have everyone try to screw everyone else. I know in the first 2 everyone had their own agenda and that was part of the movies charm, but it seems to me they went too far in the the 3rd.
Instead of letting the movie flow everything was over done, trying to top the last one (a very common problem with sequels).
