I must confess I know very little about this programme and have struggled to find anything to add to my knowledge. Consequently all I have to go on is the small exert on one of the show reel tapes that John sent me.
The scene used shows John's character, Tim losing his temper with a woman. The scene is a powerful one, with the apparent outcome being Tim hitting the woman. He manages not to. We then see him opening up about his childhood, how his mother had commited suicide abandoning him without so much as a note explaining why.
Despite knowing nothing about the character prior to watching this exert, you leave the scene feeling that you know Tim very well and certainly hold some sympathy for him. The result of a good actor.
