Reactions to the just-released trailer for 'Mirror Mirror' -- next year's adaptation of the 'Snow White' fairy tale starring Julia Roberts as the Evil Queen -- have been focused on how campy the whole thing looks. There's slapstick, corny puns and a pedigreed actress vamping it up to levels so cheesy, you'll need to get your cholesterol levels checked afterward. So yes, 'Mirror Mirror' may be an over-the-top circus, but is that necessarily a bad thing? Probably not, especially if the trailer follows through on its seeming promise to make 'Mirror Mirror' the modern-day version of 'Faerie Tale Theatre.'
