Well after completing three series i can say that so far the journey was extraordinary . Series 3 may not be the best series probably because of the second episode the three signs but the first and particularly the last one,his last vow were awesome. I fervently wish that the entire team of sherlock comes with a bang this time . And i can say that i am deeply satisfied how the series is running. Talk about favorites,Than my personal favorites were three episodes the Reichenberg falls , a scandal in Bulgaria and his last vow and the best series was undoubtedly series 2.I just hope that they never change the cast especially martin freeman
