It's an unpopular opinion for sure. Evangelion had great potential, a mysterious world, but it never reached it. I kept waiting for it to get good and then it just abruptly ended. I couldn't stand Shinji either. His situational paralysis was so frustrating. If he'd been a coward it would at least be understandable. But no, he sits there frozen half the show.
Anno Hideaki and his followers are just not capable of actually doing stories with much depth. It's all just shallow dopamine-maxxed mecha-tronic fetish paired with brutalist architecture and rushed out barely meeting deadlines. But pointing that out is like pointing out that ramen is just a single bowl meal with barely tolerable PFC balancing. Who cares. Uh half noodle garlic vegs sauce please. Yes half.
the emotions of the story are the point, not the story itself. Also, shinji is a coward. That's literally the whole point of the show, showing a cowards reaction to being forced into a situation that isn't avoidable in the most drastic way possible
