After Benedict Cumberbatch embodied the Holmes of my imagination, I have no desire to see Robert Downey Jr give a very pale imitation of Holmes, especially since Holmes's genius mind is decidedly missing from the Downey Jr version. Holmes's mind is what drew me to him like a magnet in the first place. It is what makes Holmes Holmes. Without it, what is the point?
