Seems like that’s kind of the point. The songs make up the most pivotal points of the movie rather than long drawn out dramatic scenes that you would see in a normal movie.
That’s why you see people falling in love, wife forgiving him, husband realizing what he had all along happen pretty quickly.
I don’t judge any musical on being too quick or choppy for that reason. Although they all feel that way if you are expecting a long, continuous storyline.
I thought Greatest Showman was pretty perfect for what it was and what it was trying to be. Can’t remember the last time I walked out of a PG movie that I legitimately enjoyed.
