It's an unconventional musical to say the least.
P.T. Barnum. Freaks. Circus. Rich. Poor. Prejudice. Dreams. Happiness. Commitment. The Greatest Showman seems to have a little bit of everything. But most of all it has music -- at times tender, at times powerful. It may not be historically accurate - after all it IS a musical - but it is a good story and it's a good time at the movies. Some hated the movie. I thought it was well done.
"This Is Me" is features Barnum's collection of special people. They attempt to enter a room full of high society snobs during the reception of Barnum's newest "show" - the European opera singer, Jenny Lind. But he prevents them from entering on the pretense they have a show they must get ready for, attempting to cover his embarrassment of their presence during his finest entertainment moment. So he sends away the ones who gained for him his new found success; you can almost taste the disappointment. Societal station trumps friendship - and the angry entertainers leave the theater and march back to their circus proclaiming loudly and proudly that they are not ashamed of who they are.
