Maggie (2015) https://www.imdb.com/title/tt1881002/?ref_=fn_al_tt_1
The idea of "what if your loved one became infected?" has been presented in pretty much any zombie movie of the modern times and Walking Dead too I guess, not to mention Shaun of the Dead, but probably not as deeply as in this movie. The whole question of "when does a person stop being a human" etc.
I guess it didn't bring anything really new to it, but is was still quite a sad drama to watch. I liked it overall, but not so good I need to see it again or anything. Arnold Schwarzenegger was good enough in his role of a protective dad going through the sorrow process of seeing his only daughter slowly going towards the inevitable.
EDIT: I think one review summed it up quite well that this was a special zombie movie in that it was not about survival, but about the sorrow and social aspects of part of the population getting infected.
I also liked how there was no real good or bad, right or wrong, in this movie. Different people just tried to cope in their own ways. That one police was maybe depicted in a bit negative way, how he wanted to round up the infected people ASAP to quarantine, but even his motivations made sense, maybe he just wanted to try to get rid of the disease as promptly as possible, just being as pragmatic as possible. Score: I dunno, maybe 3½/5.
