I've finally seen Eva 3.33
I'm not gonna repeat what most ppl in here said(I'm with the Y's group that enjoyed the movie and wasn't disappointed) so I'll just elaborate on some parts:
1) they weren't sure if he was REALLY Shinji
2) Lack of Trust
3) imagine that someone unwillingly killed everyone you knew/loved/cared about. and he has no recollection of doing so. Do you think it would be simple to just debrief him like that?
somehow i didn't get the meta-idea about Curse of Eva .. but damn it was so obvious(and true).
Funny thing that despite all Genou's scheming(and usurping the power as Y said) everything went according to Seele's plan up until closure of the Gate. Also I think that Kawrou had his own agenda that was unrelated to both of them(Seele and Gendou) - but he pushed Shinji a bit too much and it backfired.
