Although Rachel Weisz is outstanding in dual roles (especially as Elliot), the narrative and pacing of Dead Ringers leaves a bit to be desired. Even at just six episodes, it’s too long. There are two subplots that are completely unnecessary (especially one about the twins’ maid), and a random non-linear offshoot that is more confusing than anything else. Still, Weisz, who is a shoo-in for an Emmy nomination (if not a win), keeps it engaging even if the destination is never as captivating as certain parts of the journey. Also, beware: the blood, graphic medical scenes, and talk of miscarriages could be triggering for some.
