This is astonishing...and yet not. Having seen some of Sher's non-revival works throughout the years, I can say that developing new material is not his strong point.
There was also the problem that the (delightful) film has no plot to speak of; it's all style, quirks, coincidences, and non-sequitur asides. I'm surpised that people are unanimous that Benanti walks away with the show when her character, at least in the movie, is, like most of the characters, rather extraneous. The movie is a lark, a whim, a flight of fancy...perhaps loading songs onto it gave it a weight it just can't support.
Here's hoping they can pull it together, though.
"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
