Homeless + free??
I think of all the explanations I have read, the "all was a dream" ones make the most sense to me. BUT for those of you that say the end depicts what she really wants when the whole family walks off together & that she killed her husband in the hotel... How could she be on the streets homeless? Even if children's deaths were perceived as an accident by police which most of us agree it was not, deliberately slashing the husband's throat was murder. She would probably not be in prison considering her mental state but at the very least, in a mental hospital, not walking the streets freely. If I'm missing something... Help. :-)
I know, I know... It's only a movie.
