Arachnophobes Should Skip This Middle-earth: Shadow of War Trailer

One does not simply shot web into Mordor.

Giant spider suddenly is sexy lady....... le sigh

Spiders - why does it always have to be spiders.

I dig it.

If I can manage spiders leaping at my head in VR for Farpoint, I can survive that sexy spider lady...

Why is Shelob a woman now?

Just put a giant glass over her, slide a giant piece of paper under the glass and chuck her out of the nearest giant window. No worries.

All right, I'll try to explain what I think they were going for here...
Shelob is a giant spider, but (quick tolkien-lore lesson) she is the daughter of Ungoliant, which was this humongous ancient giant spider, and I mean enormous, big-as-a-valley big. She was this primordial spirit, sort of this lesser divinity/spirit (the same as Sauron, more or less) which was corrupted and took the form of a spider (why, I do not know, maybe she liked spiders ) So being her daughter, I figure that Shelob is also sort of a spiritual being, besides being a huge ugly spider. Talion, being an half-wraith/spirit/undead himself, may be able to see this sort of spiritual projection of hers. I do not think the sexy lady is her real body, just the way she chooses to be / is seen by Talion. I think that's what they were going for, I mean in the books it's clearly said that Shelob is not just a big spider, she has a will and if I remember correctly there's even a couple sentences about Sauron communicating with her and viceversa (without either of them leaving their respective places) so I think they're doing what they did with the first game, find these unexplored parts of the lore, that give them wriggle room to expand them and build upon them and work on that to make an original story.
Mind you, this is just my theory. Maybe the sexy lady IS her real body and not just a sort of spiritual projection/avatar of Shelob. I really hope not, though
