Somehow, I don't think the intent of the thread was to critique the movie (and screenplay) based on it's strict adherence to Scripture. Folks, try to put the film in context...1970...in the midst of the "Jesus Freak" movement that sprung up in the mid-to-late sixties. It's a film. It's a screenplay. It's a musical. The music is phenomenal, IMHO. Judge the art for what it is, not what you think it ought to be.
And its a film based on the Gospel of Jesus Christ. That would automatically mean that people who watch it will be judged against the Gospel : p If it wasnt meant to line up with the Gospel, then lets call it for what it is. If it was meant to line up with the Gospel, it didnt do a very good job.
