When I put the movie I was not expecting much and in the end I am still disappointed. An ending that feels like even the writer didn't know where he was going. The sect thing last a duration of 10min and the rest is just people telling each other to stay quiet but out loud despite knowing sign language...
Moral of the story: leave introverts alone when they want to.
What an interesting story. I didn't like it one bit (except maybe the ending) but there were some funny moments.
The brother's story was really useless though.
