I loved the movie!!! It was a great time. The use of the music was perfect. Walking out I felt that a person would have to be a Springsteen fan to enjoy the movie, but I was wrong. It's based on a true story, but it was obvious at times that there was some drama added to make the story more interesting.
My wife is not a fan and she also loved the movie and she plans to see it again when it is released.
I don't know if this is a movie that needs to be seen on a big screen. I think it would be just as good at home. If you do want to see it in a theater I recommend seeing it soon after it's released as I don't know if it's going to do very well. The free screening I went to was only about half full.
