The centerpiece of a successful Pirates movie must be Johnny Depp, and he’s back doing his drunken, rock and roll pirate thing. Jack is actually less interesting this time around. He’s not doing anything new, simply repeating the performance we’ve seen already. Well not exactly. He’s less of a scoundrel, probably because he’s too busy flailing his arms around and running to get down to good old-fashioned skullduggery. That’s the story for most of the movie, beloved characters from Curse of the Black Pearl running around being chased, trampled, and rolled down hills. Where the last movie had piracy, fencing, gun battles, and drunken singing; Dead Man’s Chest has CGI beasties and lots of screaming. here
