I tend to look askance when they are not entirely faithful to Doyle's sacred canon, but for a Brett performance I'll overlook most anything. The additonal material, while not strictly necessary to the plot, were well-chosen and allowed them to develop more of an atmosphere, probably a good move for those not already dyed-in-the-wool Holmes buffs. Those of us who have most of the canon almost memorized often forget that newer generations of fans, unlike us, may be starting fresh and this may be their first exposure to Holmes, Watson and the foggy streets of Victorian London. A one-hour block is sufficient for almost any Holmes story, but I welcome a stretched, movie-sized version when it is done well. This Holmes-Watson duo is, I believe, the best so far, and overall the large body of Holmes adventures they`left us will be the standard against which all others will be measured for a very long time.
