Law & Order: Special Victims Unit is one of the longest-running TV series on the air. It goes darker than the already-serious Law & Order by taking an unflinching look at some of the worst crimes aimed at some of the most vulnerable people. Most episodes of Law & Order: SVU are dark, but some go further than others.
