I don't understand what your point is.
If it's about the writing being bad, then I don't agree. I personally really like the writing(aside from Shadowheart), I think it flows well for a single-player RPG, especially compared to other single-player RPGs(Dragon Quest, Final Fantasy, Dragon Age, Mass Effect) it starts off strong and fun for me.
I don't understand your point about their clothing being an issue, everyone was abducted by the Mind Flayers, so they would be in all sorts of different outfits and from different places, beliefs, all walks of life.
The art style of this game is also realism. That's why they used motion capture to animate everyone. I don't understand what your point is.
Their point is about how the story is conveyed. There is more than 1 way to introduce the narrative to the player. The easy way is to just tell the player, "this is what is happening," which is easy to do and it works, but it isn't very good story telling. Alternatively you can show them what is happening through details in the world, only ever saying the bare minimum and the player then infers the story from the world around them. The latter is much harder to do, but makes for much better writing.
