Soooo many are being developed now. Seems like everything that springs to mind is already somewhere in the development stages. This seems generic, but I think Hellblazer could be done as a high quality HBO kind of show. A blue collar working magician in London... getting into all sorts of occult trouble. Seems very "open" as a concept. You can get into relationship stuff, but then the magic comes in and you never know who is going to get out alive.
