>>2858329>If Anno wanted to make people hate ReiSeveral reasons. Like you said, Anno didn't write Rei alone. There was pressure from peers and from the TV network for Anno to finish the story, and finish it well. At this point Anno didn't have complete power like he does today. He was forced to finish the series, and his original plan was to go on live TV and apologize for failing to provide a proper ending for the original.
Another reason is that Anno hated Rei because she was more popular than Asuka. That only happened after he had written most of the story and there was no way back. Anno is an anime otaku who acts just like the cliched waifufag does when it comes to favorite characters.
So it's when he remakes Evangelion that he takes out his butthurt on Rei and her fans, something he enjoys more than writing his own favorite characters. He's a shitty guy.
