I went to see this movie with my friends, I really liked the color scheme throughout the entire thing; the intense reds of Rachel McAdam's costumes, the darkness, it all added to the mystery of the complex and entertaining plot. Sherlock is an (of course, handsome) exceedingly intelligent man, and Watson is both useful and entertaining. Both of them sported a lighthearted banter of humor between them, which I felt gave the characters a sense of a realistic friendship, a closeness that, were the humor absent, wouldn't have been felt by the viewers.
