Dennis Potter's 1986 Mini-Series The Singing Detective is an excellent concept ruined by axes and flowery dialogue. It has a great central premise about a writer who only feels alive in the world of his novels, and his failure to connect with others, and it has a fantastic way of telling his story through psychoanalysis. But the story itself is way too long, with overly long dialogue scenes and portentous writing that feels more like a parody of bad playwriting than an actual story.
So, that's why I feel they should remake the serial with a more modern script that focuses on the characters more and on the life story of the Main Character. You could even add in elements from Potter's other plays, like Karaoke and Cold Lazarus. If they had this show now with better writing and storytelling and with a greater emphasis of Fraudian and Jungian psycology, then I think it would be even more of a hit than it was in late 80s when it first premired.
