BBC's Sherlock is a visually and aesthetically stunning series with clever writing and intriguing characters. It gracefully adapts Arthur Conan Doyle's stories to modern day London and it's clean, sharp, and the first two seasons are completely worth your time. I repeat, the first two seasons are totally worth your time. The third season is a complete trainwreck. If you plan on watching this series stop after the season two finale unless you want to be disappointed by four and a half hours of cringe worthy mediocrity. But like I said before, the first two seasons are amazing but for God's sake don't waste your time on the third.
