I, too, loved the Rathbone take on SH, but as I got older I found a number of people have done excellent jobs in the role. We are all familiar with Jeremy Brett's performance on PBS, but how many of us remember Arthur Wortner and Ronald Howard?? They were also quite good in the role.
The Bruce take on Watson is generally looked down upon these days but in their time most folks found them very enjoyable. I, also, prefer, the competent Watsons, but Bruce's performances are enjoyable.
