Parallel universe sci-fi is too intense for kids.
Parents need to know that this sci-fi series has lots of action sequences, as well as a good bit of violence, drinking, and sex. The main character's exploits in the underworld sometimes include scenes that could be tough for younger teens, including rape, murder, and images of dead bodies in a morgue. Because the show involves frequent traveling back and forth between parallel universes, it can get confusing. Some characters know when they're shifting to another universe, but others don't and are clearly baffled. The portals to the various universes are controlled by a powerful company that seems to be above the law. Characters in the show's world are born into a rigid class system.
