Carrie and Brody are totally awful for each other: Brody is a traitor and terrorist who belongs in prison, and Carrie is a lonely person trying to put her life back together. And yet, every scene they’re both in, however dramatic and intense, violent, tragic, shocking or crushing, is charged with sexual tension. While weaving together an ornate tale of deception both political and personal, “Homeland” is also creating the should-be mayors of Smoochtown, USA. “Just call me and tell me you miss me,” Carrie instructs Brody. It’s the cover for making him a double-secret agent. And let’s be honest: It’s a cover for a lot of other things, too. Alas, in my opinion.
