I've started this movie with almost no expectation based on critics and viewers reviews. It was supposed to be badly acted, too slow, unfinished... but, I found none of the above. The movie has two major events, one in the beginning, one at the end, the rest can seem indeed slow and boring, but I think that was exactly the point, whatever happens in the arc between the beginning and the end it's just life, little moments, which I found were very well put together to imply that life goes on and it does not have to be extraordinary every day. It was what made the movie very realistic. As for the ending, without giving too many spoilers, I will just say that I think it was quite clear, even if the authors did not spell it out for us, the message was there, one look to freeze him on the spot for the time being and one left wide open door for him to come in eventually say quite enough. The entire movie was less about words and more about acting and I think the actors did a great job acting it.
