Did you get it ? (SPOILER at the end of message)

I watched the film yesterday and I really liked it. It is one of these interesting films, that are difficult to put in a genre....that makes it more fun as you never really know what to expect. It keeps you switched on until the end of the film and hope you don't need the toilet as you might miss a few minutes. I really liked the acting, too. Every character was credible, even when they were extreme.

Now SPOILER AHEAD:












Did you get the end? I am not sure I did. For a moment I thought the whole thing was set up, as she seemed so grateful in the end....was it planned to let her undergo all that so that she will try to walk again? Was everybody part of the plot? But what about the body?

An alterntaive explanation is that she "cracked" in the end and got mad...was she so traumatized that she lost it and thought that was really great therapy? Her eyes look really insane when she is back in th car with her parents.

Elaborate on this..... ;-)
