this incredibly well made, interesting, but very scry and gory film has way too much gross contenet for most teens. even some adults may get grossed out by all the gore and killing. it does have some very well executed found-footage camerawork, but this thriller is too harrowing for older teens. there is little violence in this horror movie, but there is a TON of blood. people are seen with boils and rashes as well as hole, gashes, and flesh torn off. people vomit regular bile and also blood. dead fish are seen and are expirimented on. the film does not hold back on any details. dead bodies and gore cover a hospital and streets in some scenes. a man legs is shown being amputated (with bones crunching heard) and is shown being put in a bag. a cop shoots some people offscreen and then shoots an officer and commits suicide, all with blood spurting. a man has a video of something moving inside of him, and a bug is seen bursting out of a mans neck. there is an overall gross atmosphere and the scares with leave you shaking. there is talk of very grisly material. to make matters worse, there is swearing, including uses of s**t, and f**k (with some seen in a text) ther are other milder profanities. on the bright side, there a strong economic message: do not pollute, or a bug will crawl into you, eat your organs, and then kill you.
