This is a great series, and Jeremy Brett is as good at being Sherlock as David Suchet is at being Poirot.
I mean no disrespect at all, but I feel compelled to note that I think the above comment gives a completely wrong impression. I wouldn’t use the word “action” to describe Sherlock by any means. There is, of course, a bit of action in it. But it’s very, very far from the focus of the series.
