The romantic comedy “It’s Complicated” arrived at the multiplex on Friday complete with an R rating, ranking it in the same category as “The Texas Chainsaw Massacre” and “Basic Instinct” in the eyes of the MPAA.
But there is no violence in “It’s Complicated,”and the bedroom scenes are decidedly tame by contemporary standards. Instead, the R rating — which experts say could limit the box-office potential of the Universal Pictures film — comes from a scene in which Steve Martin and Meryl Streep share a joint.
