Have you not seen Rebuild 1.0? It's revealed that they are bio pretty early on, and for good reason. I can't be the only one who thinks TV series Eva is a little on the slow side.
Anyway, I don't think a live action movie or even trilogy of movies can be pulled off without ruining Eva as a whole. I kinda hope it doesn't happen, especially given how FUCKWIN Rebuild 1.0 was.
Remember that time I wrote a RAGE!Asuka x subservient!Shinji fic and at least three separate Anonymous were like ZOMG MOAR and then I got banned? That was fun.
