I can only remember a few words being said and almost never 2 in a row. The director will give you hints throughout the scenes as it switches from a kidnapping to a treasure hunt, or is it a reunion, or is it something else?
I think film goers should be warned when such a unique technique is used. I assume the low ratings are due to those expecting dialogue to guide one through the plot. Not this film! If you are one of those people who's losing interest after the first few scenes, don't get discouraged. this movie is VERY good.
