To be fair to the show, every episode is like a movie in itself as it's about 90 minutes long or there abouts.
I am a fan of the actual novels of Sherlock Holmes, I have the entire collection on my phone and I do read through them now and again - I can appreciate how they're trying to stay true to the character, from that time period, while putting it in a modern setting. With that said, I feel this season has sort of strayed away from that, especially from the most recent episode of this season so far.
