Steven Spielberg's new film, 'War Horse,' is racking up the accolades and being touted as a movie for the whole family. But given its subject matter -- a boy gives up his beloved horse Joey to the war effort -- is it really okay for small children? The movie is rated PG-13 for "intense sequences of war violence," but that warning from the MPAA doesn't begin to cover the trauma that Joey (not to mention several humans) undergoes.
