One review I read called the movie a "test run for the inevitable Broadway show". Every person I have talked to who has seen the movie - critic or not - has talked about how the songs have been stuck in their heads for days.
My kids saw the movie once and haven't heard the songs since then. I heard them both belting out "Let It Go" last night.
I suppose if you don't like Broadway tunes, the songs won't appeal. But objectively, this is the most musical Disney film since Beauty and the Beast.
why don't you send a free ticket to @Lee and let him be the judge? The boy done loves showtunes ... and, as I am sure you know by now, has an amazing singing voice.
Could I see this on Broadway? Sure. But not on the strength of the music. But DD's husband would be a better judge!
