I went to see this movie last night and I must say that it was AMAZING! I absolutely loved it! It was back to Jack, no overwhelming romance that dragged on too long, just Jack and his awesomeness. If you click on the picture it will take you to the Wikipedia page for the movie this will give you a synopsis and a character list with the actors. One reason why I loved this movie so much was because it not only focused more on Jack but it gave him an almost human quality whilst still going back to the first movie and joking about what he had said in there and some previous actions.
Some of the general things about this movie are: Blackbeard, the esteemed pirate of old, is the villain in this movie. The plot revolves around his need for the Fountain of Youth. Barbosa is back! Jack the monkey is here! and there are mermaids, and zombies. BUT! They are not your classic mermaids, they are beautiful, they can sing , they prey on sailors, yes, but they have deadly fangs almost like vampires.
I would definitely recommend that you go see it, but if you do, I suggest you study up on your lore, and your Pirate movies because you will need it to understand some parts of the movie. Have fun, oh and look out for a Harry Potter character in your movie going experience because I assure you if you look carefully enough you will find one.
