That's not pretentious. It's a fucking introduction trying to explain the show. It just outlines the plot. And that's what the series is about.
I've never seen another series remotely like it this side of Tezuka, and it's introduced very interesting philosophical ideas I've never conceived of before. Therefore, I believe it to be a remarkable, intelligent, and highly unique series.
The only reason people like you keep saying it isn't remarkable is because you're just annoyed by the hype. But really, you're only making it worse by making people like me disagree with you and forced to prove my point. So if you want the show to be less hyped, stop telling people who love the show and think it's great that it's not so great.
I'll admit one thing though. The first episode was the best one and since then the show turned out to be something different than I'd hoped. It's not exactly what I wanted, but it's still pretty damn good.
