"You can pay attention to the actors more, and the story is more intimate. Not all shows should be big broadway musicals."
I still think some people aren't getting the point here. So let's try again.
The book of Funny Girl is not good. It's the music and the production numbers that pull the show up.
If you strip down the production numbers and lessen the instruments in the orchestra, it will emphasize how bad the book is. It would take a supremely talented actress to rise above that.
Funny Girl was touring around in the 90s. Was it Debby Gibson doing the tour? The reason it didn't come to Broadway was that it was a stripped down version and everyone realized without a full orchestra and big production numbers, the show ain't good.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
