i'm pretty familiar with RDJ and Cumberbatch's Sherlock, and i LOVE both of their portrayals. but now I kind of understand why my dad, who loves these stories, doesn't like them. this first story is basically the first episode of Sherlock but with SO MUCH MORE! i liked it a lot! it was fun to compare the actual Sherlock Holmes that Sir Arthur Conan Doyle wrote, to the ones i'm so familiar with. highly recommend to other Sherlock fans. I'm definitely going to continue with the series.
