I finished watching the series.
I really liked the earlier episodes set in Memorial Hospital, during the Katrina disaster. But the post-Katrina episodes felt distant, as two leading investigators take over the narrative. Try as I may, I just couldn't sympathize with their struggle. Perhaps their narratives would've been more effective if the series started with their scene.
My main problem is Anna Pou. First of all, I think Vera Farmiga did a phenomenal job playing this complex character. But the series robbed her of the pivotal scene where she is (more or less) resigned to administering the controversial shots.
I liked the series overall and it helped me educate on the side of a disaster I wasn't aware of. But the series felt incomplete.
