Oh haha you mentioned the two that I did not watch at all :D so I can't comment. What were the receptions for those? I heard book fans usually prefer book version..I guess this is the same for IS as well.
I didn't go in depth for L&R as I wasn't part of the crowd back then, but what I've read from some of the novel readers was that ML (Yu Sifeng) did not actually get tortured like what was being portrayed in the drama. I'd guess they added more 'spice' to the storyline (ˊᗜˋ)" This drama became a hit in 2020, bringing upon fame and recognition to Cheng Yi, who is actually a veteran actor of nearly a decade old (surprise, surprise!)
For WRTW, there were mixed receptions because the drama differs very differently from the novel, so novel readers tend to see it as a separate entity.
