There were many movies and series about Sherlock, some were good and some - really bad. This series is nothing new. It is like female version of the latest Sherlock portrayed by B. Cumberbatch only... it is worse. Quite boring to see a copy of Sherlock & Watsaon's behaviour from other series. So, no thank you.
PS. It is not a cultural thing as I am not native English speaker and I rate it 3 stars.
