Gormenghast?

[saintbacchus]

I was wondering if anybody had seen/read this series.
See, this is applicable because there are three
Harry Potter actors in it: Zoe Wanamaker, Fiona Shaw,
and Richard Griffiths.

Because of that, I keep running across it when I'm
looking for Potter stuff, and, well, it looks utterly
fascinating. Just look at this site and try not to get
excited:

So what I want to know, before I run out and buy the
DVD is, is it good or just pretty and well-cast?

Any info would be greatly appreciated!
