I saw this Thursday night and was very pleasantly surprised, as my expectations were biased a bit by the kitschy theater I've seen in mainland China (although the ending drifts into that territory IMO). I completely echo your praise - this is a really special work that deserves a bigger audience and a better title. The current one undersells it and borderline misrepresents it.
On a side note, I got a kick out of how many people were taking photos (and with flash!) in the completely darkened theater.
