Sherlock. Season 3 episode 2 failures

1) The Case

Would you come to a detective  in the evening and torture him with your case, being aware that he is drunk? I wouldn`t. Why she leaded him to the "crime scene"? For what? For him to lose conscious there? And where was Mrs. Hudson? Why she didn`t show the door to the nurse once she saw her? The case really wasn`t a life and death question, she even didn`t look frightened that much. The scene was so long and doubtful that cause disappointment. There`s enough humor in the series.

2) Her Majesty's Household Guards

I doubt that it is allowed to common people to walk in the building where the guards live. The first two soldiers ought to have noticed him, I can`t find any reason why not.

3) The Wound

If you can easily feel a paper cut, how thin the blade must have been for the guard not to feel it? Show me, please!

4) The Case (again)

The case was just too easy for Sherlock to solve it that long. Even I began to suspect the photographer even before this scene.

5) Drunk Sherlock

Hmm... On the one hand, I don`t remember any connection between Sherlock and booze. On the other, he smoked and took drugs (in original), what he doesn`t do now, so we reach balance this way. But: Sherlock began to resemble Sheldon too much. It must be Sheldon who resembles Sherlock, not vice versa. Actually, they are quite similar... but Sherlock doesn`t have stupid habits, caused by psychological disease, which Sheldon has (and a lot). So he shouldn`t gain Sheldon`s manner of behavior. My thought: Please, don`t make him Sheldon! DON`T MAKE A SITCOM OUT OF "SHERLOCK"!

(Actually, they don`t seem to. Prepare a shock blanket for the episode 3;))
