If you missed the Sherlock episodes, start right now and watch them all. As a series, it’s different than most — each episode is like a movie and each season has only 4 episodes. Season 1 began in 2010 and the final episode of season 4 aired last Sunday night — don’t expect a new season every year. Rumors have it there may not even be another season… others say it is coming in 2-3 years. I’m hoping for the latter.
