For some reason the IMDB raters give Mirror Mirror a mediocre rating. Maybe I'm just in a happy mood these days, or my standards are even lower than usual, but I found it enjoyably watchable all the way through. (Also: it was free, being one of the University Near Here's summer film series.)
Julia Roberts plays the evil queen, risen to her position via her feminine wiles and abusive magic. Her latest conquest was Snow White's dad, who she maneuvered into apparently fighting and losing to a fearsome forest monster. She abuses the kingdom's subjects for her own extravagant appetites. Snow grows up fatherless and neglected, and in mortal danger. She finds unexpected help from Prince Alcott, a handsome good-hearted dim bulb. And (of course) seven height-challenged lads, after initial misgivings, become allies as well.
Things are mostly played for laughs, and Ms. Roberts especially seems to be having a lot of fun. There is—out of nowhere—a big Bollywood-style finale, worth sticking around for.
