I see a lot of 10/10 reviews on here and while I agree that the show is entertaining, it's not a great mystery series. I don't notice it until the end of the series but Sherlock isn't really that we'll written. If you rewatch the series you'll notice how there is never really a logical conclusion to crimes. In the old stories by ACD, you are presented with evidence as you go along with the story and when the mystery was solved, it was done in way that explains how the crime was solved and makes you realise that you could have solved it yourself if you paid attention. In this series it relies on 'epiphanies' ,the whole mind palace thing and withholding evidence to the viewer. Too many times sherlock would come to a conclusion but it's never explained HOW he came to it, and that you need to trust him that he just knows it. The show acts like he's so smart that you'll never get how he knows what he knows. In fact, the show proves this by having sherlock point things out that have no impact on the case but is just there to show you just how smart he is. The production and action is very good, but suffers from poor writing and inability to explain, and need to go over the top with certain stories. If you want a better sherlock Holmes interpretation, watch Elementary. It's not perfect, but it's certainly a better detective series.
