Huh, No actually, it sounds worse.
While it's weird to fetishize Sylvanas because she's still technically "dead", at the same time she's still an elf, so that's understandable (not justifiable, but understandable).
Meanwhile Shelob is literally (or was literally?) an ugly spider, how are you going to turn that creature into a beautiful woman, it's just weird
I am willing to make the same argument about Alexstrasza and Ysera btw.
The implications that Sauron (while in his hot form) was having sex with human Shelob are also weird and really out of nowhere.
NOTE: I said "weird" and not "bad", because I actually find it funny that Sauron had the time to develop a whole relationship with Shelob in-between scheming and deceiving people, but it's still weird because it came out of nowhere. Before that videogame came out, everyone pretty much agreed that Shelob was just a giant spider and that was the end of it.
Although this is lore-breaking, because it doesn't explain why Shelob tried to kill Frodo and Sam, when their mission was to destroy Sauron (that Shelob, in the videogame universe, hated and despised after he betrayed her).
