Well, Despite the obvious difficulty filming team had to deal with to make this movie, I believe they couldn't make it! Maybe little changes would round it's rating to a brand higher level. For instance, with a brief background story for the leading actor, it would be more convincing to what he was doing(Being mad at sth).
However, I think maybe the whole movie was a metaphor of how much one may risk for a better life , safety and family.
BTW it gets 3 out of 5 from me.
