No, and I don't think movies should have the movie rating system, either. I'm tired of everyone being so easily "offended" and wanting either the government or some other agency to step in and make their decisions for them.
Adults should be perfectly capable of deciding on their own what they choose to see or not see; and parents, not some anonymous group of bureaucrats, are responsible for policing what their kids watch. Parents just need to do their jobs.
As adults, we don't need these self-appointed "babysitters" making these decisions for us: it's dangerously close to outright censorship.
