As unnecessary sequels go, “The Devil Wears Prada 2” (20th Century Studios) earns a well-deserved place near the top of the list. Where the original, released 20 (!) years ago, had iconic lines (“That is all.”) and portrayals (Meryl Streep should have won an Oscar for her performance, as opposed to the undeserved one she received for the abysmal “The Iron Lady”), the sequel is lacking.
