I agree wit Jason as well. They took Blackbeard which is a legendary pirate and the only non-fictional pirate in the movie and made him into a completely fake pirate with powers.
I liked the movie but was not as impressed as i thought i would be. It lacks a lot of action and jumps from scene to scene randomly(bad plot). Everyone has their opinion and i think On Stranger Tide was my least favorite out of all four. But still that does not make it a bad movie as II'S PIRATES OF THE CARIBBEAN WERE TALKING ABOUT HERE!
