Remy- The Fades
Okay, disclaimer, BBC TV owns life. I make no qualms about hiding how The Misfits (first two seasons) is the best show I have ever seen, and The Fades seems to be from that same school of adult themes not watered down for a younger audience, as is the case with American TV.
The Fades was about a young man who could see the dead (not in a Sixth Sense type of way, but more in a Heartless kind of way), and lived in a world where he tried to learn to balance both of those realms he was trying to coexist in. Fades are the name for the dead who have not left the Earth (for various reasons), and Paul (an angelic), is trying to figure out a way to stop the fades from bleeding fully into our world and destroying the human race. While it was only six episodes long, and told a concise story in that time, for a television universe that was ripe for the picking, six episodes was just not enough for what they could have potentially done with that idea.
