Why is it the men never survive?

Rating: 5/10 (7 January 2019)

If you have seen A Quiet Place, The Happening, Cargo, The Mist, The Road and Day of the Dead (Remake) (probably a bunch of others) you've seen this film. Predictable twist ending a la AQP.
Apocalypse scenario.
Group of survivors.
Must ultimately get from point A to point B (Sanctuary).
Must have at least one supply run where one person dies.
Have one or more people betray or abandon the group.
Have women in the group whom cause the death of the group. Either through sexual competition among the men or doing something insanely stupid that leads to multiple deaths.
At least one "sex" scene of two people polar opposites knocking boots because it's the end of the world - in this case a drug dealer and Police Cadet.
Let in a stranger who is infected or is a "bad person" who leads the the death of one or more people.
Feminism on pause as men sacrifice themselves to save the women/the group.
A fairly decent way to burn through a couple hours if you are into apocalyptic movies. But it's all been done before and better. I would have liked to see a twist where the (two) people who abandon the group actually show up at the last scene in the Sanctuary.
