I watched this trying to understand better the facts of Covid and it unfolding since I only really heard stories from the news. This did an okayish job showing that as it mostly pertains to 3-6 patients examined in the whole film. Oddly they threw in a racial component to the film that seems unrelated and disjointed (they do mention that apparently covid affected minorities more than white people but that's unrelated to the BLM stuff they have later in the film).
Overall I had more empathy for nurses and what they went through so I'd say that's probably the message overall that resonated with me.
