Sherlock mode of address

Sherlock insults everyone without even knowing he's doing it, also Sherlock reads people to understand what they are like which isn't normal showing just one of the ways in which Sherlock is different than normal people. Another key thing is sherlocks costume with the long black coat and scruffy black hair which give Sherlock a very mysterious look but he also has a very sophisticated look by wearing a suit underneath which confuses you about weather Sherlock is supposed to be seen as.  Shows johns past in flashback of when he was a solider (gives a back story to the character) police press conference setting makes it more serious along with cuts to different people taking poison shows the genre of what the programme is going to be very early into the episode, awquad reunion of john meeting an old friend shows how unsocial he has become as at first he doesn't recognize his old friend.when Sherlock is asked by Molly he doesn't understand and notices small things like when she puts lipstick on to ask him out, this shows that he is an outsider and different or unique than everyone else. Sherlock can get so much about a person from a tiny little thing like how when him and john are riding over in the taxi he tells him lots of personal information and then it does a flashback with close up 3-d panaramas of John and the phone zooming in on the important things.when Sherlock is looking for clues at the murder scene he finds things that even the police don't find which can sometimes get him in trouble or get other people in trouble like noticing about the Sargent and the phorensics team man wearing the same deodorant. Then when he figures out that the killer has made a mistake which he can see and he dashes off no one else has no idea what he's talking about and he has to explain most things that he does. Mysterious car pulling up after phone call adds to the genre and intreges the audience to wonder who it could be.
