Just saw it in Denver today! I loved it. They ended the first act with Let it Go and everyone was in awe as the lights went up. Loved the extra songs. Loved olaf and Sven. Loved young Anna - she was perfect! Loved the special effects. I won't say anymore. It ends in Denver Oct 1. They will spend the next few months tweaking and reworking things before it opens in NY in Feb. I wonder how much of it will change. My family loved it!!
