If you are looking for a thrilling show of detective things than this is probabaly the best show. Hats off to benedict cumberbatch who performed Sherlock’s role so deeply and Martin Freeman as John Watson. All seasons are exciting and mind blowing, I’ve watched all the season of Sherlock and I can definitely say that you will like this show if you are interested in detective shows. Stefen Moffat has done a lot of work to convert the orignal work of Conan Doyale into a show that would be a great hit. Watch the seasons and enioy.
