Back when I was watching cql but hadn't touched mdzs someone--(was this you @rhinefall?) said the show had really overemphasized the pseudo-familial, fraternal elements of the story, at the expense of wangxian.
(Which I found deeply off-putting ngl because it makes it sound like the show made up a lot of the meaty content there, which it did not. Its major invention in that area is jiang cheng's crush on wen qing.)
And it's like. Looking over them both. I can see where that statement is coming from, in that The Untamed frontloaded jiang cheng, gave jiang yanli extra appearances, and generally expanded the ratio of page/screen time for the backstory in order to let that carry more of the obvious narrative arc. Since the romance arc could not play out as in the novel, due to censorship.
But being able to compare them now, I honestly feel like what cql actually wound up exaggerating most was...wei wuxian's relationship with lan wangji???
Because. They had to take the romance out. But they also had to make them love each other or there's no point. Which means wangxian had to be friends.
Which in turn means that in the live action version teenage and young adult Wei Wuxian consistently pays attention to, focuses on, confides in, and routinely interacts with Lan Wangji very much on purpose, as part of a relationship he values, considers strong, and is making an effort to maintain.
None of which is true, in the novel.
