I haven't seen the show, but a 2 hr 45 min running time to tell this story seems really bloated. The movie was 1 hr 38 min.
It's not Lawrence of Arabia or Gone With the Wind. Nothing "epic" in scope here.
It sounds like the biggest problem is trying (really hard) to showcase every single character in the ensemble cast. Everybody gets a moment or two or three or five to shine. The movie featured a lot of great characters, but their time to shine was (mostly) brief with a lot of impact. It left me wanting more from all of them which is always better than wanting less.
They need a show doctor, pronto, with a ruthless ax, to start trimming the the excess down---including cutting songs, scenes, and truncating the dialogue. They need to drive the story forward and quit trying to push every single performer for a Tony Award.
A musical comedy with too much material is deadly.
