I will say that when I watched it, the "older people sacrificing themselves so the younger could live" really didn't come across to me as the tainted symbols of the old regime having to die at all. (Though I imagine it'll be difficult to read it otherwise for anyone having read those reviews ahead of time.) I mean... if anything, to me the allegory read as, those who want to break the system have to take some of the brunt of the damage. And I don't believe the line in that review that Yona is some kind of untainted pure soul; her connection to her father feels way too stressed in the narrative for that for me. I mean, if nothing else, there's the drug connection; sure, it's his hallucinogenic escape from the reality of the train, but it's also implied that he got her hooked on the stuff.

I dunno, I enjoyed it, but I wasn't expecting something DEEP that would BLOW MY MIND, I expected an action/SF movie with a central narrative driven by other-than-USian obvious-narrative-choices.

If it's just gonna annoy you at this point, though, there was nothing so supremely amazing in it that I think it's worth watching through for.
