The melody that is heard while Sherlock smashes the casket is reminiscent to Vesper's theme from Casino Royale (2006). Both the movie and this series were composed by David Arnold. See more »

How the mighty have fallen
19 January 2017 | by ian-litchfieldSee all my reviews

After being thrilled by the first three seasons of Sherlock it was with dismay that I watched the 4th season slide ever deeper into a convoluted mess. I am actually quite surprised the actors actually agreed to make this crap. The story in "The Final Problem" is so bizarre I think Moffat must have been on the same drugs Holmes used in the previous episode. Totally unbelievable throughout, it tries to be way too clever for its own good and ends up being stupid, and worse it makes Sherlock look stupid.

If this is the way it is to be from now on I would say please don't bother with another season, not unless you get a new writer. I give it 5 only for the fine acting which was the only thing that made this bearable to the end.
