I think this has to be one of the most moving films I have ever seen in my life (after The Passion of the Christ). The story is filled with themes such as redemption, grace, forgiveness, mercy, and love.
I have seen it on the stage two times and have been moved every time. But the film version brings a completely different dimension to the story. The actors actually sing their parts "live" while filming. This made the story so much more REAL. To see a close up of an actor crying while they sing made them seem like they were right there in the room with you living out their lives. I've really never experienced anything like that in a movie.
Bring a fist full of tissues with you and enjoy this well-written, well-acted, well-sung, well-produced, well-directed story.
