DREAMGIRLS...what changes would you make?

Now that we have a movie in the works and a potential revival down the road I was wondering if any changes need to be made in the plot. I think there needs to be a little more clarity to why everyone thinks Effie is so difficult. In the stage musical there's also a reference to Curtis and "...all the drugs" that comes out of nowhere. And just for fun...I wonder who Brenda Talbert and Bertha Jackson were?

ehhh the show is 2+ hours already. We don't want a Wagnerian opera. I think it's fine the way it is personally. I don't thinkg Deena and Effie need a "sing-off". Deena already admits she's not the singer Effie is. Lorell can't sing lead because there's only 1 lead singer. It kinda screws with the central drama of the show. I also don't think that Effie has to be big. It makes it a bit more dramatic I'll admit. She has to be more ethnic and soulful than just big. They mention her getting fatter only because she's pregnant. i dunno I really think it's a really well put together show. CC having a thing for Deena is kind of interesting though. If there's time it might be nice to see it explored a bit. It's already implied. I dunno it might take the focus away.

O if Effie dies as I have been hearing she will...please don't bring her back to life at the end of the movie. Geesh.
