SUICIDE WARNING
I have seen several reviews with this critique on different sites, so I will say this here:
Some say that they didn't feel Zabo was depressed enough to be suicidal and the ending came as a shock to them. I felt the ending was exactly what I was expecting, and if it ended differently, it would have felt fake and contrived.
While I have never attempted, I have been in a place of desiring the end of it all, and my head space felt very much like this movie. The circumstances of my life were different, but the feelings and questions and indecisions had the same themes and ideas (this movie seemed to be my thoughts taking on solid form). I am still not sure if I should have seen this movie or not it followed my feelings to a bad place so well. As Pol said, "If you make an enemy of life, you make friends with death."
