Excellent movie, but ONE thing bothered me....

Rating: 9/10 (10 December 2019)

Well acted, scripted... fun for all the mystery lovers out there. However I had ONE issue that came to mind, a while after I returned home from the movie. I would've given it a perfect 10 otherwise.
After the injection incident, Harlan carefully plotted an elaborate exit strategy for Marta which would take him at least 10 minutes to explain. He would've died within that time frame if the medical explanation held true. BUT he didn't die... should he wait another while before ending his own life? He would've realized everything was FINE with him afterall. But then again, the movie wouldn't have been made. My bad...
