Same here, I was prepared for disappointment like with Downeys movies. But It was good, I was even impressed with the opening music, and this from a big Basil Rathbone fan...
Basil Rathbone and Nigel Bruce were great. Unfortunately they had to work with some really cheap productions.
An interesting note. In one of the old movies, Dr. Watson sings “Loch Loman” with a girl. Sherlock tells him he is good enough to appear at the Royal Albert Hall and he is right. Bruce could really sing.
