people are going crazy over this . its interesting details are - each episode is 1.5 hour long and four-five episode in each season . Sherlock's logical deductions are too refined . he does not fear anyone , which makes him super and unbelievable . detective monk has his blessings and weaknesses too which make him endearing . here each episode is like mini movie . many things are unexplained like Sherlock's hacking skills . Watson is a bit okay . Mycroft and his dumb assistant add humour . lack of human affections is another downer for Sherlock . crimes are a bit illogical too . they are unsolvable because no motives . the landlady is quite lovely with her soft accent .
