I am a big fan of the Granada Sherlock Holmes series as I have said many, many times. This may not be exactly faithful to the original story, while Moriaty was a very welcome presence compared to the original story he feels rather thrown in and there are some very memorable and humorous bits of dialogue that didn't quite make it on screen.
However, on its own terms The Red Headed League is very, very good and reinforces what I love so much about the series. As always, a lot of care is taken into how well constructed the adaptation is visually. The photography is very skillful, the costumes beautifully tailored and the scenery and sets wonderfully meticulous and atmospheric. I was too taken with how Sarasate was portrayed and the lengths that were made to make the actor look like the violin virtuoso.
The music is once again wonderful, with themes that are both beautiful and haunting. The story is well paced and interesting, the dialogue is sometimes humorous but very often thought-provoking and the direction is solid. The acting is excellent as is consistently the case with this series. Jeremy Brett with his towering presence and gritty baritone of a voice gives a very commanding title role performance, and David Burke is a thoughtful and composed Watson. Eric Porter also does very well with his appearance as Moriaty, his performance is somewhat brief but that was a decision for the better, too much Moriaty and I personally don't think this would have been as effective.
In conclusion, maybe not as strong as The Norwood Builder, The Crooked Man and The Speckled Band, but a strong episode. 9/10 Bethany Cox
