The Greatest Showman had promise - it failed with the Broadway musical approach.

Sets were constructed as if for a broadway stage (low budget and poorly executed by movie theater standards). Musical numbers were catchy and relatively good, but did not fit the movie or the venue.

The bottom line is this - if I want to see a Broadway play, I will go to New York City and see a broadway play. I do not want to see a Broadway play on my local movie theater screen. (Fences was a perfect example of this failure, and now The Greatest Showman is added to that list!)
