Both these episodes are superb in every respect. Brett at the top of his game, Burke and Hardwicke, in the respective episodes here, both peerless. But The Final Problem has the bonus of Eric Porter as Moriarty. This was the first portrayal of Moriarty I had ever seen on film or television where Moriarty became alive. Porter made him just as I had always imagined him but had never seen from any other actor in 50 years of viewing various Holmes offerings. The verbal exchange between Brett and Porter in Baker Street has EVERYTHING - great dialogue, fantastic diction, beautiful timing, fantastic silences and glances. Any aspiring actor should watch this. It is an acting masterclass.
