The downside of spending so much screen time on Robertson is that the film ends up giving equal narrative weight to the black widow theory of Cotten’s death, which I find frankly preposterous. Despite the aspersions the movie casts, there are pretty straightforward reasons why Robertson has had three last names in her life: She was born with one, married into another and changed it to the third after her divorce from her first husband. Her first husband is very much alive, and she hasn’t seemingly benefited financially in any way from Cotten’s death and had to be put in a safe house at one point because of threats from former QuadrigaCX customers.
