Clearly, Johnny Depp loves playing wonky pirate Captain Jack Sparrow. And we love watching him. If only the first trilogy of films hadn't gotten so bogged down in all that nonsensical multi-film mythology. Here, at least, producers have given us a single, self-contained story. Seems Jack has been suckered by an old flame (Penélope Cruz) into searching for the long-lost fountain of youth with evil pirate king Blackbeard (Ian McShane) hot on his heels. The film is much tighter than the previous installations, but sacrifices a bit of the oversized wonder in the process.136 minutes PG-13.
