Critic Reviews for The Final Problem

Rather than illuminate the complex fabric of the show, as good series finales do, The Final Problem poked holes in it, pulling any threads of narrative consistency apart.

Whilst this wasn't the ending some of us will have been expecting, the journey to get this far has at least consisted of more highs than lows, with a heavy vein of experimentation throughout.

This finale represents a fitting end to the foundation of the show that had been there all along, even if we the fans had put up new moldings and installed new floors.

It's daft but we're damned if it isn't entertaining.

Apr 12, 2019 | Full Review…

Instead of truly reckoning with those emotional crises, the Sherlock season four finale is riddled with improbable showiness, melodramatic conclusions, and logic-defying puzzling turning points.

The Final Problem was an interesting thought experiment, but a disappointing episode of Sherlock.

Apr 12, 2019 | Full Review…

For a show that seems to want to be smart and make a statement, it feels lazy.

[The Final Problem] is bold, daring, and incredibly emotional. Shock twist after shock twist is handled well, even if Sian Brooke's Eurus is so over-the-top that it can become an irritating rather than terrifying performance.

Apr 12, 2019 | Full Review…

One part psychological horror film that never quite had the balls to go all the way, one part self indulgent trifle, and one part metaphor for hell, the entire souffle spent a good portion of the story threatening to collapse under its own weight.

Apr 12, 2019 | Full Review…

The Final Problem is full of ludicrous twists and unearned revelations, and despite that fan service-y closing montage, Sherlock ends, for the foreseeable future, with a messy, unsatisfying finale.

Apr 12, 2019 | Full Review…

[The Final Problem] was fun to watch. Fun and ultra-tense with a terrific, whooshing sense of momentum.

Apr 12, 2019 | Full Review…

The Final Problem is 90 minutes of great television, perfectly balancing the emotional journey of our title character and the quirks of an exciting new mystery to solve.
