Two major issues. We have a better movie to watch.

Rating: 4/10 (29 December 2018)

I don't understand why some people think this is a good movie. Probably they don't use their brain while watching a movie. (Sorry)
One issue is in the first 15min. They start the movie with a scene of the three, the main character played by Sandra Bullock and two kids. Then the movie go back to five years ago, the time nothing has happened yet. Then, about eight people decide to hide in a house, including pregnant Sandra Bullock. So it's obvious that all other adults will be GONE. To explain this apparent thing, three-fourth of the movie time is used.
It's like that a movie "mist" starts with a scene in a car with four people. That movie didn't spoil itself like that. It seems so stupid. The composition doesn't make any sense.
If people know this is a survival type movie, the ending is usually either survival or death. That being said, they wasted a large part of the movie by this awful layout of scenes, and nothing left to watch.
The second issue is its unexplained convention about the effect on people. Most people become suicidal, but some people don't go suicidal under the influence of the "creature". And those who can see the "creature" play a major role in this movie, but nothing explains what divides these two groups of people. Does it indicate that prisoners or "bad people" don't become suicidal? If so, that's a very outdated sense of sin and crime.
In short, the majority of the movie is wasted for already revealed plots, and the cheap "happy" ending doesn't ensure any safety against the creature and other people who don't go suicidal but kill others.
This movie wasted time of great actors and actresses, so don't waste your time as well by watching this movie.
