Sheltering Season

This could have been a good movie, but I don't know what happened, can't quite put my finger on it. The best thing about it was the drunken friend who at least was interesting and veered off course.

I get that it's during an epidemic, but a lot of it just didn't make sense and the whole drama with the three main characters never really gripped.

What was the purpose of the supposed "militia?" The ending was an absolute farce. He tells the cops about the fire and they check it out and confirm everything, but they don't go back to house with him even though they know his wife is in danger? And another one that "leaves you guessing" ho hum.
