It's a shame, because this movie had so much potential

And I know it because after watching it last Friday, I have been dreaming of it two nights in a row. This just happens to me when a movie leaves a bold impression. Besides although I was able to identify way too many flaws while watching the movie, I really was entertained during the hour and 30 minutes.
I found the storyline had so much potential, reminded me of a mixture of The Believers and Man on Fire with a refreshing twist. However the ending was too confusing and the director didn't make the slightest effort to clarify the mess. Too many twist and turns at the end. I like a story with a twist, but too many of them could be too risky and in this case destroyed the whole movie.

Are you not entertained? Are you not entertained? Is this not why you are here?
