I, for one, quite enjoyed the 04 DS Pilot. The only thing it suffered under was the direction, as many involved with the project have pointed out. Having read, and owning, a copy of the script, that was completely solid, and much of what was on the screen followed what was in the script. Only thing that detracted heavily from it was the ending, but I thought it was a fair start for something that would get better. Because, let's face it, most show pilots suck compared to what comes later.
And if the WB Pilot had've been made this year, for this fall's line up, it probably would be picked up. It seems that just after the 04 pilot was made, like others have pointed out, is when the off-beat, supernatural, mysterious etc craze really started. I mean, we have Supernatural, Heroes, Bionic Woman (coming up), The Sarah Connor Chronicles (also upcoming), Pushing Daises (yet another upcoming), Medium, Ghost Whisperer, Moonlight ('nother upcoming), and who knows how many I've forgotten to list. Sadly, DS was before it's time, yet again.
