I think this is the fifth of Disney's Pirates movies. But I wouldn't swear to it in court. The problem being that, despite some very entertaining moments, the chaotic scripts all blend into one another. (Anyone remember what 2011's On Stranger Tides was about? Or what happened at the end of 2007's At World's End?) This time around, we've got Johnny Depp's Captain Jack Sparrow searching for the mystical trident of Poseidon. Also, a ghostly Spaniard (Javier Bardem) is trying to kill him. Also, Paul McCartney is in it. Sure, it's fun. No, it's not a coherent narrative.129 minutes PG-13.
