Cars 2 opened to lukewarm reviews and a smash box office, taking in $66 million domestically and another $42 million internationally during its opening weekend. The film’s ability to transcend unusually tepid reviews is clearly a testament to the power of the Pixar brand (another gift of Steve Jobs), which has generated a remarkable series of animated hits stemming from the Toy Story franchise that began in 1995 and continuing through gems like Wall-E and The Incredibles, as well as the first Cars. But this film also carries a loud and unmistakable message about alternative energy, automobiles and their shared future.
