Can someone explain this comment from Ebert's review?
"Beneath these two levels (the coming-of-age journey, the two Mexicos) is hidden a third. I will say nothing about it, except to observe there are only two shots in the entire movie that reflect the inner reality of one of the characters. At the end, finally knowing everything, you think back through the film--or, as I was able to do, see it again."
If anyone knows exactly what he is talking about, I'm interested.... I have a clue but I'm not 100% sure. If you are, please respond.
