So many attempts and so little success. Looking for successes I think the latest incarnation of Dune, although flawed in some aspects, was probably the most successful of the 3 (4 if you count the aborted Jodorowsky attempt). I think the Jackson Lord of the Rings was very good even without certain sections (sorry Tom Bombadil, you just aren’t central to the plot). The Expanse did middling well, though I lost track of it mid 2nd season.
The failures are more plentiful. Jacksons Hobbit was a mess with unnecessary additional characters and subplots, even though the acting (Bilbo and Thorin especially) was superb. The Foundation series by Apple mangles the timeline (mostly because with the longer timeline there is no character continuity but for the shade of Hari Seldon) and adds wokish subplots all over the place. Effects were nice and Asimov having ONLY humans in Foundation/ Robots universe simplifies that. All in all it was a disappointment and I bailed after 3-4 episodes. I think it fell flat for the public because many of its ideas seemed like retreads (E.g. Trantor as a planet covered with civilization feels like warmed over Coruscant even though Trantor predates Coruscant by 20+ years and likely inspired Lucas). And Rings of Power? Mauling the lore of Tolkien to pander to a variety of subgroups combined with puerile 4th-grade fanboy scripts produced an utter catastrophe.
Almost anything Sci-fi that Hollywood has done without a sci-fi novel or story at the heart is a mess. Hollywood seems to want to revert to the pre Star Wars Sci-fi where all is Dystopia and nuclear hellscape. That things might work out is anathema. Even the vaunted Federation of Star Trek has been being mauled with its hidden perfidy in Discovery and Picard. Not to say dark is bad. Babylon 5 was amazing (especially given the limitations of cost and mid 1990;s special effects).
What seems to matter most is that the primary vision for converting the Sci Fi to the screen needs to LOVE the material. JMS wrote much of B5 and was its director, Peter Jackson Adored Lord of The Rings and co-wrote the script, Denis Villeneuve is a Dune/Herbert fanboi. Each loved the story in its original form and tried very hard to leave the original plot beats and characterizations in place, not bend them to tell their own story like Rings of Power or Foundation did.
Of the book based Sci-Fi movies of which I’m aware, the one that was most true to the book was the original 2001. Both Jackson’s Lord of the Rings and the latest version of Dune at least try but both are handicapped by intricate and massive substrates that are almost impossible to set up and capture in the context of 2 hour +/- videos. Although Blade Runner was barely related to it’s source material, “Do Androids Dream of Electric Sheep”, by Phillip K Dick, it succeeds on it’s own as a brilliant piece of work. Though the Star Trek movies… Read more »
