While also a controversial adaptation, Sherlock's bold and unique take on the Sherlock Holmes world earns it a spot on this list (at least the first two seasons!). Sherlock introduced most American audiences to the now-beloved Andrew Scott, Benedict Cumberbatch, and Martin Freeman. Taking the world of Sherlock from the grasp of the sultry Victorian era and into modern-day London was a bold move.
It may not be the most faithful adaptation, but its clever setting switch allowed the writers to modernize the universe and comment on humanity's ever-changing values throughout the eras.
