The Marvel Universe has wizards now? Yes, and “Doctor Strange” is the movie where we meet them. But more than anything, this is a character study of Mister Doctor himself, who is laid low by distracted driving and then has to rebuild his life by moving to Nepal, stealing books from a magical library, and getting half-frozen on the side of Mount Everest before being thrust into mystical battles against his will. Spectacular visuals! Mads Mikkelsen trapped in a wall! Tilda Swinton as a super weird ageless magical being (who was Asian in the comics)! Dormammu, we come to bargain.
