The writers seem to have confused cleverness with convolution, twists and turns. The best thing about this series is the interaction between Holmes and Watson, and even that is on the verge of turning sour. They promised and promised that there would be no love interest between the main characters, but as we get closer to Watson leaving, I get a stronger and stronger feeling that Holmes is developing feelings for Watson - especially after the end of this episode. The series is growing stagnant - hopefully mid-season will give something to spice it up and break it out of the case/catfight of the week.
Also, OMG, product placement much? I was disgusted by the blatant advertising by Windows 8 and Surface. Way to sell out, Elementary. Let's NOT go there again, alright?
