Then the "delusional drunk" Doctor is my favorite Doctor.
Really? What is it about his performance that you like? Because from where I'm standing, we're looking at an actor who constantly undermines the dramatic tension of all scenes, who seems so bored by the scripts and so underwhelmed by the cardboard monsters that he plays everything for laughs, and who's become so full of himself that he refuses to make eye contact with his acting partners. By that point, his once sharp and witty Doctor had become increasingly frivolous and clownish.
I won't say that Tom Baker never was entertaining during the Graham Williams year, because he regularly was, but the quality of his performance very rarely rose beyond the level of panto acting.
