Even though I enjoyed the first two movies they don't exactly rank high on my list of the best movies. I feel more or less the same about the third one. It's a lot more confusing, it has A LOT of stories, the break in the middle of the movie (in the cinema) was well needed, so I could get my thoughts together and figure things out. Also, some of the stories have disappointing endings, like the Davy Jones/Calypso, I wanted to see her mess things up, instead she just created a maelstrom that wasn't much of a threat.
Orlando Bloom and Keira Knightley will never be my favorite actors, they do a poor job, also because they're not really believable as real pirates. It's an entire different thing with Johnny Depp, Geoffrey Rush and Ben Nighy though, all incredible actors, especially Nighy, who is one of my favorites. Sparrow is probably Depp's best role ever. Chow Yun Fat is so cool too, he's a ninja pirate for god's sake! Too bad there was no proper sword fights with him.
The CGI, mainly Jones' tentacle-beard is the most realistic looking digital special effects I have ever seen. There are especially two scenes that are awe-inspiring, first is Jones grapping a tear from his eye with a tentacle, second is the rain pouring down on his face. Just amazing. Too bad there was no scenes with the Kraken running amok.
The ending was all right, Will becoming captain of the Flying Dutchman was a cool idea, although he looks more like an Italian model than a pirate. At least it wasn't a typical sugar-sweet ending. Sparrow going after a new trasure was neat as well, would've liked to see Jones and Calypso making up, or at least confronting each other too.
Decent flick, Pirates of the Caribbean: At World's End: 6/10.
