Hi,
Aside from the really bad directing of some of the shows that grossly mis-use Christopher Franke's music, the show is actually good, and interesting. I would have been a bit more riske with it, to make things more appealing to a wider audience, but the show was stuck with too many poor choices, for directing and defining their next story, in my book.
There is no excuse to use anything, music or sound included as just a filler. It cheapens the product and hurts the overall design.
When you listen to Christopher's releases on his own, they are much better and have much more continuity that the series was afraid to touch.
