Mycroft Holmes: What you're about to see is classified beyond top secret. Is that quite clear? Don't minute any of this. Once beyond these walls, you must never speak of it. A D-notice has been slapped on the entire incident. Only those within this room, code-names Antarctica, Langdale, Porlock and Love, will ever know the whole truth.

Sherlock's season 4 begins with a touch below the expected
3 January 2017 | by mtgsebseanSee all my reviews

It seemed like centuries since I had popped down on the couch for the newest episode of Sherlock. Dare I say I ever doubted the arrival of the new season, as I spent my days checking the Twitter account that counted down the days until the new episode. Without a doubt, the first episode of season 4 has been one of the more lacking entries in the series' history. For the first hour or so, Sherlock and co. investigate a newer case that Lestrade has handed them, along with the expository re-introduction of the cast. Even early in the episode you can see how the writers intended for there to be a focus on the matrimony of John and Mary. As the episode dwindles on, Sherlock solves the first case easily and the plot deepens. Unfortunately, going deeper is not what the episode needed. We find out about the huge spy-associated history of Mary, and the mysterious flash drives and their connections to her team. This entire story is built in one episode, and it is the centerpiece of it as well. This decision by the writers backfires, because the actual flesh of the story is not only unnecessary but at times boring. As viewers have come to see a show about Sherlock, they are immersed into the Watson world of Mary and John's boring adventures. From an irrelevant 'love' side plot of John and a random bus passenger, to Mary's affairs in the spy world, the episode lacks any real entertaining substance. Mary is followed by Sherlock to the destinations she wishes to hide herself, thus making the whole idea of her hiding herself unnatural and unneeded. Another issue is some plotshielding throughout, which allows the characters to go about things altogether unrealistic. Although the episode uses the concurrent themes and music from the past seasons, its main focus is astray from the brilliance of the Sherlock series- and that is Sherlock himself. The great thing that lifts this episode above a terrible rating is the acting. Even though the writing and plot bores me, Cumberbatch and Freeman once again deliver exciting portrayals of their characters. By the end of the episode, there is a deep gash in the cast, with Sherlock and John divided for 'classified reasons' (I wish not to spoil). Hopefully this gash will be the interest of a new story arc to power the next two episodes in season 4. The first episode just lacked interesting detail and function for the latter half. Please, Moffat, don't disappoint me like you did with Doctor Who, and bring season 4 home with some exciting content.
