It started okay but went further downhill the longer it went on. It's really hard to believe NO ONE else in the town could fight the aliens, the whole 'self forgiveness' plotline/ending was confusing and honestly dumb. If she had no one in town who cares about her, why would she stay and willingly be a social pariah? What happened to her parents? Did she face repercussions for killing her friend? Why were they in the middle of the woods in the first place?
This movie makes the viewer ask A LOT of questions, and answers NONE of them.
