I agree with most of these, but I gotta cut Disney some slack for the Little Mermaid and Hunchback. Hans Christian Anderson had an unholy love for sad endings – his TLM was an original story, not some ancient and beloved traditional Marchen. He’s the one responsible for bringing that unnecessary sad ending outtta nowhere, and having the Mermaid turned into seafoam and dancing with the angels. The ending of the Disney film was needlessly bombastic (someone has pointed out that it’s practically the same as in "The Call of Cthulhu!), but to me still preferable to the original. (I prefer the Disney ending even more to The Steadfast Tin Soldier in Fantasia 2000 – in the original Anderson snatches a sad ending from the very jaws of a happy ending, to no point that I can see.)
As for Hunchback – NO film version I’m aware of it faithful to Hugo’s book. What’s lauded as the best screen adaptation – Charles Laughton’s – also leaves Quasimodo alive at the end. Why should Disnet take all the flak?
I hate the “adaptations” of Starship Troopers and I, Robot with the heat of a thousand suns, but at least in the case of I, Robot I see what happened – the guy was trying to write an original screemplay set in Asimov’s universe, and they morphed it into something else with a halfhearted attempt to pass it off as Asimov’s book, managing to completely subvert the original tone, message, and philosophy in the process. I hated The Puppet Masters, too – it could’ve been great. Having read the screenwriters’ accpount of its genesis and development, I realize that it could’ve ended up worse. But it still ended up pretty bad.
I think Lynch’s Dune deserves a lot of credit – it could’ve been better, too, but it did try to be a work fairly faithful to its source (at least a helluva lot better than Jodorowski’s version would’ve been) yet not slavish to it. He even used John Schoenherr’s original paintings as a guide. The film has great visuals and moments of brilliance, but I think they bit off more than they could chew with a novel that long.
League of Extraordinary Gentlemen I could understand – Connery was the exec producer – no way he’s going to make his Allan Quartermain an ineffectual drug addict. And they weren’t going to open themselves p to charges of racism with that war of Fu Manchu’s Chinese mafia. Or put in Moore’s omnipresent rape fantasies. It coulda been a lot closer to the book, and still been effective, but at least I understand where it’s coming from. And the introduction of Dorian Gray and Tom Sawyer (!) were at least done in the spirit of the original.
This is why I don’t think there should be an adaptation of Watchmen – it’d be too long, too involved, and they’d dumb it down.
Practically all adatations of Poe, Verne, Wells, and Lovecraft are pretty awful. There are rare exceptions.
And I pit every adaptation of Twain’s A Connecticut Yankee. Every version screws with it abominably – even the one on PBS. Maybe someday they’ll come up with a version that’s not a vehicle for a “Star” (Will Rogers, Bing Crosby) and retains Twain’s irony and wit.
