As always, if you saw that before reading the books, there's a risk you got hold of the wrong end of the stick, so to speak... I saw it, umm, a few months ago, and (again, as always) it didn't look very much like how I had "seen" it in my imagination. But -- surprise! -- I really *liked* how it looked anyway!
Hmm... Is this "the exception that proves the rule"? Or could it be a more general "exception", that the rule isn't that hard-and-fast if it's been a couple decades since you built it in your imagination? I dunno which...
But anyway, this reminds me: Don't get over-entusiastic and try to foist the books on your kids, if you have any in their low or mid-teens. _Gormenghast_ was pretty heavy fare even for a voracious reader like Yours Truly, at ~seventeen.
