BBC’s “Sherlock” takes characters within the Sherlock Holmes novels from a 19th-century London to its 21st-century counterpart. Created and written by both Steven Moffat (the head writer behind Doctor Who) and Mark Gatiss (again, a Doctor Who writer), as well as Stephen Thompson (yup… he also wrote an episode of Doctor Who).

There are currently two series, each with three 90-minute episodes. It stars http://en.wikipedia.org/wiki/Benedict_Cumberbatch as Sherlock Holmes and http://en.wikipedia.org/wiki/Martin_freeman as John Watson. It’s unfortunately not available on BBCA, but the first series is on Netflix and and both series can be purchased on DVD/Blu-ray.
Here’s a trailer for the first series:
