Why Is Bullet Train Rated R? What Parents Should Know Before Letting Their Kids Watch

The first thing that just about any viewer will notice about "Bullet Train" is that the film is incredibly violent. People are sliced to ribbons, blown apart, and one unlucky character even takes a meat hook through the head. All the same, the fact that the movie often plays these moments off with a note of dark humor helps to keep the tone of the film from getting too grim or overbearing. "Bullet Train" also contains a sex scene. Though it's only quickly seen through a passing window, it's definitely graphic enough to see exactly what's going on. 

Finally, the film also contains a lot of foul language throughout. While this can be a concern in and of itself, it's unlikely that if the excessive violence isn't too much for your kids that a few swears are going to be the deal breaker. All in all, it seems to be the consensus that younger viewers in their mid-teens should be mature enough to handle the material in the film.
