Great series, one of the best British series I have seen. The series' most special feature is the acting, especially from Benedict Cumberbatch, who played Sherlock Hummels to the fullest extent. I cannot accept that any other actor will play Sherlock Hummels after him, and the characters in the series were great about the character of Sherlock Holmes and John Watson and their friendship, the two biggest flaws in the series, according to me, was Sherlock's intense intelligence. I had hoped his smarts were a little lower and the series went down in level last season, but it's still a great series and it's rated seasons. Series 8.5 / 10 for the first, 9.5 / 10 for the second, 8.8 / 10 for the third, 8/10 for the fourth, and the series as a whole 9/10.
