First off, I have to say that I loved this movie. However, it is very violent and dark (e.g. dead bodys hanging from nooses, in coffins, and one naked in the bathtub, though nothing sensitive is shown), and one scene is highly sexual (again nothing explicit shown), showing a woman getting dressed in her hotel room with Holmes present (we only see her naked back, but it's implied that Holmes sees more), then drugging him. When he comes to, he is completely naked, except for a pillow covering his privates, and he is chained to the bed. A maid comes in, and seeing Holmes, gasps and drops the stuff she was carrying. Holmes tells her that "The key to my release, is beneath this pillow", and she, making a shocked face, runs out. That is all the sexuality that you will see however. Very violent fistfights abound also. In two of them, Holmes looks at his opponent, and thinks of a way to hit him that will completely disable him (you hear him thinking out his plan, so kids can memorize his technique, and it shows him acting out his plan in wince-inducing slow motion), then he does it in real time. The language isn't much worse than what you would hear on most T.V. shows, so no worrys there. I do not normally worry about drinking in movies, but in this case, I make an exception, as not only is there casual drinking, but after one particularly violent fistfight, Holmes gets extremely drunk on something apparently meant for eye surgery. Despite all this however, it is an excellent movie, depicting London at the time of the movie perfectly. Also, the script and acting are great though I will not reveal too much of the story. Also, overly religious people might be disturbed by the use of black magic by the villian. I am Christian, but this didn't really bother me. The movie also has a very good chance of causing kids to develop an interest in science and deduction as well.
