Johnny Depp and Penelope Cruz in Pirates of the Caribbean: On Stranger TidesPIRATES OF THE CARIBBEAN: ON STRANGER TIDES

During the first hour of Pirates of the Caribbean: On Stranger Tides, the third sequel in Disney's hugely successful franchise, characters are routinely told to beware of the mermaids - half-woman/half-fish beings who use their comely looks and tranquil siren songs to drag seafaring men to their deaths. Our adventurers take note of the warnings but pay them little mind, and really, why should they? Disney, after all, is the studio that gave us the benign cutie-pies of The Little Mermaid and (through its Touchstone Pictures label) Splash. Just how nasty can these things be?

We eventually find out, and as a result, I'll likely never look at Ariel or Daryl Hannah the same way again.
