>>69504005You can easily understand what's happening, even if you don't get all the crazy symbolic bits.
Plus Fuyutsuki explains most of what's happening before instrumentality starts.
Sandbox scene = Shinji looks at his life and the fact that he was always alone and saw people as dolls.
Misato sex scene = Shinji being disgusted that Misato is a whore, but at the same time kinda jelly.
Asuka being a bitch scene = Asuka being a bitch
Then Shinji chooses what gets to happen to everyone, then he realizes that run away is pointless and cancels instrumentality.
The One More Final really puzzled me though, but that's normal.
I got this from my first 2 viewings and didn't need any guides.
