I really think it comes down to the individual. I personally think that Aldous Huxley’s book Brave New World was likely derived at least partially from the book We by Russian author Yevgeny Zamyatin but both Aldous Huxley and my 10th grade English teacher would disagree. I don’t think it’s wrong to take someone else’s work and add upon it in a way you view beneficial. I view it as a natural evolution if anything and if it gives someone something to enjoy or makes the creative processes a little easier I’m all for it.
This is something I’ve struggled with. I read a lot of trending books in high school like Hunger Games and Twilight but ended up reading 50 Shades of Grey to the end and it honestly turned me off of reading for a while
I’m not the fastest reader so it really seemed like I just wasted a lot of time
