Over the last couple of days I've been watching the BBC television series Neverwhere which was written by Neil Gaiman.
I'd been aware of Neverwhere for some time, I've never read the book but I had heard that Gaiman was interested in producing a film based on this series and I can see why, there were some interesting ideas in Neverwhere but the series was severely hampered by it's low budget and I think a moderately budgeted movie exploring the same ideas could be interesting. - as it stands I think I could only recommend the Neverwhere TV series to die hard Neil Gaiman fans and having never read the book for all I know they might hate it.
