The problem is not that anyone needs to see the movie again to get the messages, but rather that the messages are so simplistic and obvious that the plot is too predictable.
Why is the choice the hero has to make such an obvious choice beween good and greed? Why couldn't the choice facing the hero be more complicated so that the choice was less obvious?
None of the research I have done about the movie suggests that it has any complicated message that I missed.
