The characterizations of these literary figures are generally very good, even if their stories are altered more or less drastic fashion. Caliban is easily one of the most book accurate portrayals of Frankenstein's creation ever filmed, even if he's not nearly as ugly as the dialogue makes him out to be. And that f**king ending of Episode 4... did
not see that coming. That will be Cvalda's favorite part if she ever watches this.
Oh, and I fanboy'd out when Victor Frankenstein and Van Helsing were doing science-y stuff together.
