Very good sci fi is more intense than the first two films.
The film Riddick is the third in the series. It is more intense than the first film (Pitch black) and the second (The Chronicles of Riddick). The story continues (spoiler alert!) from the end of the second film when Riddick kills the leader of the Necromunguls and becomes king himself, when he starts the search for where he came from, he is deceived an left for dead on an unknown planet. The film is most definantly not for younger children there is frequent graphic bloody violence and gore, strong language including f**k and s**t and more foul language, the film even has some sexual themes and nudity.
