By that logic, nobody should be allowed to do a modern version of Shakespeare. Must Romeo & Juliet be set in Verona, with underage actors, all wearing those baggy clothes?
Nobody is saying that people shouldn't be allowed to do anything. Studios can do whatever they want with IP they control. My point was, that if you are going to make an adaption of an established IP, you are better off choosing a producer and director that actually like and respect the IP. That way we end up with more Fistful of Dollars and fewer Rings of Power.
Fuck that. Great works are great because they inspire variants and recreations. They're not static, fragile flowers that can never be touched.
I've seen enough recreations to last a lifetime. For example, we've never had a single X-Men movie where the X-Men look and act like the X-Men. Why don't we get one single accurate X-Men movie before we start working on those variants and recreations. How is it a bad things for people who like a book to want the movie based on the book to actually follow the book?
That's called moving the goalposts. You
were complaining about people trying to "fix" stories. Not about whether they like and respect the IP.
Hell, Peter Jackson's LotR is widely loved and considered one of the best adaptations -- and he "fixed" a fair number of things, like dropping Glorfindel to put the emphasis on Arwen and Aragorn, having the elves appear at Helm's Deep, and turning Rhys Davies into the butt of every joke, not to mention all the stuff in the Return of the King. Fixing is inevitable; it's a different medium, with different demands, plus you have to deal with stuff like studio execs who want more romance.
Fans like you claim they want pure adaptations, but that's simply not true. What you want are
good adaptations. When they're good, even the most radical adaptations are fine (do you know what story
Clueless is based on?). But when they're bad, you spout all this crap about fidelity and being true to the authors that's ignored if it's good.
And what people like varies, even among fans. Lots of people think X2 is excellent, or Days of Future Past was flawed but fun. And they might not have worn costumes, but Logan may be the single most highly regarded movie based on any Marvel property. That they don't fit your needs... well, tough. Think of the poor Fantastic Four fans.
