Most ruined character
For those who have read Russell Hoban's book, which character(s) from this movie do you think were "ruined"? My picks would be the Tin Seal, mostly due to her design. The book illustrations show her actually made of tin; while the movie shows her more like a real seal. Plus the kingfisher, in the book he was sort of a pimp/fisherman: He would decorate her in all these brilliant fishing lures and send her underwater to sing these siren-like songs to catch fish for him.
Also during the fight scene in the book: "There's Manny Rat up there on the tower all alone, and without a spear. What if I flew up there and finished him off right now?"
In the movie: "Hey now boys, we don't stand a chance, they've got guards up there, and they've got spears...with poisoned tips."
