Somewhere in the middle of this maddening mess, the Snow White story is obliquely wedged in and Winter's War goes from prequel to sequel. It makes no sense, but it does let Theron and Blunt, dressed to thrill in Colleen Atwood's costumes, go at it in full-tilt boogie. The film lets rip with the crumbling of ice castles and other forms of mass destruction. But nothing can match seeing Theron and Blunt try to out-camp each other, providing the only glimmer of entertainment in a film dedicated to being ponderous.
