Horror about a global infection which induces suicide and decimates civilisation. A gripping film which draws the viewer in, even though many of its set ups, tropes and twists are almost laughably predictable. Maybe mixing powerful scenes within a well-trodden narrative was intentional. I imagine my slight reservations about the obvious plot are informed around having seen many similar narratives. Besides, the effective pace, delivery and central relationships and group and family dynamics may have been lost in a trickier, more involved plot.
