It seems that many of the viewers are the wrong one's.
For once this is a no bumbum lazer tju bang story. This one is about human relation. One persons journey inwards. It has a deep psychological story. Very calmly told. Silence being a big part.
It reminds me of "all is lost" (Robert Red.) although not reaching the same fantastic level it is still very good.
As far from "deep impact " and many other idiotic action movies as you can get.
