Life is not easy to begin with ... but what when something terrible happens ... and what happens while you don't even know it happened? This is quite the realistic view on how things may play out in a situation in real life. So much so, that some might find the movie itself boring (or annoying).
But it is well made and it has quite the powerful central performances. The fight, the struggle, the sadness ... all to find a conclusion. The ending may feel like a letdown to some (and there is only one of two ways this can end, so that is not a spoiler, it'll depend on how you feel this should end), but overall this is a well made thriller, even if it was made for TV.
