This series is just amazing, Benedict and Martin are really great actors, I've even seen the late actor Jeremy Brett's Sherlock Holmes, I've seen RDJ's Sherlock Holmes, but this is really good, I wouldn't suggest this if you are looking for a light hearted show as this needs full concentration while watching and 2-3 episodes might need a re-watch as they might be confusing, but, it's still a great series, even the music is mind blowing(My personal favorite is "The game is on"). Definitely, worth a watch.
