Well, I'll take a crack at it.
I watched the movie, and I liked it, but the message I suppose could be a bit unclear. However, I took from it that the one person with a face was essentially up against society, depicted as the masked beings. No matter what the person with a face did, he couldn't change what was already there, ultimately saying that it is extremely hard, if not impossible for a single person to change society as a whole.
But, I could be wrong. Either way I liked it.
