We finished Sherlock last night on Netflix. It's been on our list for a while, but we got notified at the beginning of the month that it's disappearing on Monday (30 March), so we decided we'd better get off our asses.
My word, what a rush! Highly recommended if you're a fan of modern interpretations of Sherlock Holmes, and you think you can manage four seasons of three-to-four 90-minute episodes each before Monday. :-)
