I didn't believe anyone could do Gormenghast either and truthfully I was a little disapointed that the enormity of the story didn't really come through. I watched it all anyway, if you don't they won't try again with something else.
Don, The Kracken Awakes would be great. There should be lots of locations where people have walled up supplies for the millenium and don't need them anymore :)
How about Sytranger in a Strange Land ?
