Almost the perfect episode until the last 20 minutes. They didn't have to make it so complicated. The story was great , the setting was perfect and the acting as always was impeccable. Not going to go on about the story but just lightly summarize the drawbacks and the SHERLOCK moments. The episode as it stands I feel didn't need to be connected to where we left in season 3. The story and the setting was good enough for it to be stand alone episode. Though I did enjoy the subtle scene references from the main Sherlock. More importantly the episode for god sake just needed have a good solid ending. I am sure most of the viewers would complain about how the makers tried too hard to pull off a "SHERLOCK" ending. It just needed to be enough to quench the beaming desire of the fans for another year as they wait to see their favorite detective on his adventures.
What I did enjoy about the episode is as is the case with every sherlock episode is the dialogs. They take a moment to seep in and when they do: wow. The references to the main series are also enjoyable. For the first 1hr the episode hits the high standards it has set since its inception, but where it does falter is in the last 30 minutes where just needs to wrap it up in good solid way.
No matter for that, Sherlock fans will definitely enjoy it. To sum up, the episode as Moriarty would say if he was to represent the whole series: MISS ME
