Common Sense Note
Parents need to know that 10 Cloverfield Lane is loosely connected to 2008's Cloverfield, but it has different characters, a different setting, and a different approach: Rather than a monster movie, this is a sci-fi thriller in which the threat is kept a mystery until the climax. There's sci-fi/fantasy violence, as well as explosions, deaths, guns and shooting, knives, bottle-smashing, some blood/bloody wounds,and some other startling images (dead, rotting pigs; a woman with a gory face; a loud car crash, etc.). Language is brief but does include one use of "f--k" and one use of "s--t." Sex isn't an issue, though the female lead is shown in her underwear in one sequence. Characters drink homemade vodka in one scene, mostly for medicinal purposes (and a laugh). Some teens will be disappointed by the dissimilarity between this and the original, but many will be interested in seeing it.
