As far as horror movies go, this was atrocious! The acting was bad, the plot was dumb, characters were stupid, and script was terrible.
The lowlights included ludicrous underreactions to loved ones dying. Something tragic would happen and we would get about 10 seconds of poorly executed terror, then the characters would go back to normal. Much like when characters in a video game die and disappear... the dead bodies just vanished in this movie. "No burial, let's just leave our daughter's body under the camper."
The level of delusion of most of these characters was nonsense. Lots of stating the obvious, but no action to help themselves out of the situation.
I did enjoy laughing at how awful it was, which is why I gave it 1 star.
