Specify. Preferably without treating this as a discussion in a different forum, since some of your comments to/about me are inching awfully close to a line.
Taking what other factors out?
I gave up on Doctor Who prior to Capaldi's final season. I never watched Jodie Whittaker's stories, not because she's a woman, but because I finally had enough of Clara and the dumbed-down writing.
Exactly. Denis Villeneuve's excuse for making Liet-Kynes female was that he claimed there "weren't enough strong women" in Dune.
That's utter BS. There is no female character in Dune who is NOT strong, in some way or another. If he wanted that specific actress, all he had to do would be to cast her as Harah. Harah is actually a rather significant character in the first three Dune books, even without being one of the main characters.
Oh, wait... he opted to omit Alia's birth and toddlerhood, so Harah (who basically took over raising her when Jessica proved to not have a maternal bone in her body when it came to a Pre-Born daughter) didn't have that reason to be part of it.
You don't see me mocking you for that opinion, do you? It's your right to like that character. For me, Starbuck is a male character. I don't care which actress might have been hired. And I actually did try to like nuBSG. It failed to entertain me, so I stopped watching it.
My pronouns are "she" and "her". That should be inferred by my usertitle.
It's your opinion that I'm wrong, btw. I don't get where racism comes into this, unless you're suggesting that men and women are different races.
In that case, why not create more female characters?
I will admit to one case of genderswapping I don't mind, but then that particular one was something that became fanon, and was never canon. TPTB stated the character was male, and never changed that. The fans, on the other hand, include people who prefer to think of the character as female, and have written numerous stories portraying that character as female.
The character to whom I refer is Aithusa, the baby dragon in BBC Merlin. So in this case, Aithusa is a nonhuman character who isn't voiced by anyone because there are in-universe reasons why Aithusa doesn't speak. There are numerous fanfiction writers who prefer to portray Aithusa as female, for whatever reasons they have that preference.
When it comes to other nonhuman characters, it's dizzying to try to keep up with Spot, on TNG. Is Spot male or female? Or is he a male cat who got pregnant and had kittens? Did Data just have multiple cats and named all of them Spot? I don't recall that the show or movies ever clarified that.
If you don't know someone's pronouns, it's okay to ask. Or just notice the usertitle.
So, then. It's "illegitimate" for me to prefer that male characters are male and female characters are female when remaking a series or movie, even when there are sound reasons to keep them as written in the source material.
O-kayyy...
"That poster" is in the room.

And you had better not be referring to me as a "real bigot."
Here's the thing about Dune. I first read it over 40 years ago, and have read it many times since. I saw the Lynch movie in the theatre (whole different experience to just seeing it on a little TV screen), and I really have to laugh at the numerous people who have claimed that there's no evidence of any relationship between Chani and Liet-Kynes, so it doesn't matter if Liet-Kynes is male or female.
Except... "I am Chani, daughter of Liet" is a line that's in Frank Herbert's novel, and it's in the Lynch movie. So I call BS for that reason alone in Villeneuve's boastful claims of being "faithful" to the novel. There are many more reasons why it's obvious that he wasn't faithful to the novel, some related to why Liet-Kynes is a man rather than a woman, but I won't go into those here (and yes, I know Lynch got some things wrong as well, but at least he never did pointless genderswapping that proved he didn't think too hard about the actual background of the story).
There's not a lot of difference between calling a specific person's opinion bigoted and calling the person bigoted.
Well, since there are numerous things I didn't like about nuBSG and nuDune, I guess this isn't directed at me, right?
When a major SF literary work is adapted, yes, I do prefer that it be as close to the original as possible. Same with Shakespeare. There have been numerous homages to Romeo and Juliet, for instance (West Side Story is one), and that's a different situation from just lifting Shakespeare's dialogue and setting it in some other place and time where it makes no sense.
As for "extreme"... nope, not extreme. I know there can never be a "pure" adaptation of Dune, simply because we don't live in that universe and there are some things that can't be reproduced on a stage or studio. A pure adaptation would (for example) be everyone speaking either Galach or Chakobsa or any other languages mentioned in the novels. There hasn't been a single adaptation of Dune that didn't get something noticeably wrong, including Lynch (the stillsuit design, weirding modules, making it rain at the end), the miniseries casting issues (William Hurt made a flat, boring Duke Leto, and Susan Sarandon was several decades too old for the part she was cast in), and Villeneuve's bizarre choices in casting and how he portrayed the Harkonnens, etc.
It rather depends on if the person who adapts the fiction is honest about making the changes and doesn't just hit the audience with a "GOTCHA!" and makes excuses that don't make sense. At least fanfic authors tag their stories as to whether they're canon-compliant or not and how they differ from canon (if they do), so the readers can decide if they want to continue.
My take on it is there's never a reason to get incensed if someone else doesn't like the same fiction you like. That is the behavior of a child.
Example: There are some people on this forum who, even 15 years later, have never forgiven me for not liking the nuTrek movies, and have yet to let that go. They
still bring it up. On the flip side, there's a Doctor Who fan who profoundly disagrees with me about a story I really enjoy, yet he loathes. Guess what - we've agreed to disagree, and get along fine.

This is so hypocritical.
