First thing that I'd say is that the Cinematography is excellent. I love the soft colours, the slow camera sweeps. The continuity was good and the plot, contrary to what was said by others, is quite plausible, though from a medical angle (and I think from a Psychiatrics point of view) it could have been made simpler. I like the musics.
Claire never gives up, and the the characters that she meets along to and in Harris were all common characters that we see in our daily life, and this add the ease in which one "accept" the plot as we go along watching, eg that guy Bobby (Joe/Tommy's partner), Granpa etc.
It was a tear-jerker, definitely not my genre, but it was pleasant, it doesn't disappoint me, and I am not unhappy that I spent a good Saturday afternoon watching it. Will tell wifey when she's back from her own on-call, that I watched a good movie today.
