I could be ignorant about it, and compare this movie to other films like "Saving Private Ryan", "Titanic", or even new musicals like "Once", and say that this movie isn't nearly as moving, well-made, or good as them...which would be true.
But, as a true fan of movies, I can't deny the significance of "The Jazz Singer". It was the first movie with sound..that is, "synchronous" sound, meaning sound that is actually coming from the actors and not a score added in post-production. And, it wasn't just a gimmick to showcase the new technology...I was actually really entertained, and quite moved by the message of faith and family. Not to mention Al Jolson's delightful and magnetic performance. I'd be stupid not to recognize and acknowledge this film for what it was at the time rather than what it is today. This is a proven classic, and for good reason, and there's really only one rating that would do this revolutionary film justice, a full five stars.
