The filmmakers made sure that the disfigured man looked really disgusting, and the idea is rather challenging, especially because I'd lose my appetite if I shared a table. That doesn't look very good (what's the difference between me and the racists?).
The movie is too slow and not very interesting, as if the makers relied only on the curiosity of this shitty-looking and not much else. Those who mistreated this guy should have been portrayed in a more convincing way, because they just look mindless, as if the director was desperate to make them look bad, just in case we wouldn't notice.
