My 10 and 13 year old children have seen a lot of PG13 movies, but this one is definitely one I wish we would have skipped. Violent images - people burning in a plane crash, getting run over by a runaway subway train, a mother killed in a car wreck - were disturbing even for me. These in addition to Nicholas Cage drinking bottles of booze throughout the movie, weird sci-fi alien people that stalk the children, and the planet being destroyed in the end, killing everyone on it.....I wish I wouldn't have taken my kids.

My husband and I took our daughter this weekend, who is 11, and it was a pretty intense movie for kids. We thought the movie was pretty strong for even adults. It may be better suited for children 14 and up.

As we watched the beginning of the movie, my daughter and I felt slightly disturbed but convinced ourselves that the movie would get better. We have never been more wrong! We just sat on the couch and watched it spiral downward into the big finale that creeped us out and left us thinking about the new definition of "child catcher!" We would NOT recommend wasting your money OR TIME on this flop!

My 13 year old saw this with a friend. She came home horrified. We read the reviews together beforehand and watched previews, but that did not prepare her, or us. She told me the violence was graphic, with lots of blood and suffering. The animal scenes bothered her. Her main complaint were the scenes of possession. She decribed the eyes of the possessed girl, then recounted the girl enscribing with her fingernails and blood. The most disturbing aspect I believe for my daughter was the end - spoiler alert - when the world was destroyed. This is her first movie without a happy ending. Sometimes there are no happy endings, but that is a pretty heavy knowledge for a young kid to bear. I've gotten a little trusting of my daughter and movies she sees lately, but I'm going to rethink things after this.

This movie has a lot of excessive drinking done by a Dad that seems to suffer from no side-effects by doing so. The makes no buffer zone for death and shows the whole act. I would not recommend this movie to an adult let alone a teenager.

I would have given it less than 1 star. My daughter (15) & 2 sons (10 & 11) wanted to see it, but from the trailer, I thought I'd check it out with my daughter first. Thank Goodness! First of all, right off the bat the SH*T word loudly and more than once and frequent drinking out of the bottle by the main character. Then the story line was absolutely ridiculous going from seemingly "real" situations to aliens coming & taking people to another planet. But most of all this movie is VERY disturbing! Explosions with people being flung in the air and running around on fire--I even had to look down it was too vivid, then subway car off track smashing into people including woman with a baby, then animals running through the forest on fire. But the most disturbing was the little girl that wrote the prophecy is found with a vacant stare on her face under the gym in a closet trying to scratch the prophecy on the door until her fingers are bleeding. Creepy! And the alien stalkers who are men in long black trench coats that are seen standing outside the car or house staring into the window. My sons would have needed therapy if they had seen this! One scene has these strange men driving up and luring the little boy with their "whispers" to the car to give him a rock---(which we never figured out what all of the rocks' purpose was in the movie.)---much like the scenario that all parents cringe to even think about our kids talking to strangers in a car! The ending is truly stupid! Everybody in the theater just looked at each other with confusion. It was the absolute worst movie I've seen. DO NOT WASTE YOUR TIME OR YOUR MONEY ON THIS MOVIE AND BY ALL MEANS DO NOT TAKE YOUR CHILDREN TO SEE IT!

KNOWING is a fine film that is as good a thriller as it could be, and an engaging thinker as well. However, often it borders on pure horror. The film tells of an MIT professor, John Koestler, who recieves a scrap of paper with random numbers on it. (Read no more if you don't want spoilers!) It turns out the numbers predict disasters on this planet that lead all the way up to the end of the world. Yep, it's dire, and it's what the whole film is about. Soon Koestler finds himself emerged in horrific occurences: disasters that claim countless lives, and several disturbing supernatural occurences. The violence in the film isn't particularly graphic, but you feel what you don't see. One particularly harrowing scene shows victims of a plane crash burning to death. Another shows wreckage in a subway accident claiming numerous lives. Several people get in accidents that cause death and injuries. And, in the end (okay, now really stop reading if you don't want it spoiled for you) the world comes to an end as everyone on our planet dies. Just like that. Other scenes are horrific and revolve around insanity and mysterious supernatural beings that stalk Koestler and his son. The two main kids in the film are constantly in danger, so that will be a touchy point for younger viewers. On the plus side, there is no sexual content, and language is mild. This is not a film for kids. Absolutely no one under 14 (or maybe 15) should be allowed to watch it. It is wonderfully made, but it is very disturbing. Don't say you weren't warned.

i have watched knowing and im 8 years old BIG MISTAKE im mostly scared of some men on it that always come out at night and it has scary music to it but the scaryest bit has to be when there are a girl and a boy in a car and the women and and a man in a deserted house and thease men come and start wispering to the children and the boy beeps the horn of the car and the man runs out grabs a gun and runs into the bushes and then he sees the man with hin back turned and the man turns round opens his mouth and a blue flash comes out and he diserperars and the man with the gun his eyes go all blurey and i shut and then i opend them and they where blurey ha ha .

I thought it was going to be kind of like a Nicolas Cage "National Treasure", which my kids love. Tried to get past the little girl in the closet at the begining, but the scary "Twilight Zone" Men in the front yard, we had to turn it off. Thank goodness my 7 yr old missed the subway wreck. Not good for kids. I do not like the PG-13 Rating.
