Score: 4 out of 5.  This movie is very convincingly told which is a strong complement because the story could easily go dumb at any point but does not. The director and crew should be proud of this  product.  The acting is very good and very convincing even at times that one might expect it to fall apart.  My only reason not to give a more perfect score is at the very end of the movie it falls into a predictable style ending.
