I felt this movie was a 6.5-7. It could have been better, but it did hold my attention, for the most part. Without the right cast to move it along, though, I would never consider watching it more than once. That's my entertainment viewpoint.
However, from an enlightenment viewpoint, this movie's a 10. The awareness of owning diamonds to the cost of the human lives involved should have had similar results that owning furs had to the value of the lives of animals; as if humans don't lose life or its quality via brutality and oppression, given or received. Hmmmmm.
