I agree, Kad, but sometimes it's just thrilling to be able to sit back and watch a great star knock one out of the park. It is, but not at the expense of the show. Remember when PROMISES, PROMISES added two songs for Kristin Chenoweth based on this type of logic? HELLO, DOLLY is so perfect as written that I don't think it needs to have more songs, and I don't think we can really argue Dolly is an underwritten role, it's one of the juiciest roles for a theatre actress, musical or not.
I doubt much will come of this, but it's an exciting prospect. I don't mind the idea of Reba's accent any more that I mind a black, Latina or Asian Dolly, I have enough creativity to imagine reasons why Reba ended up there, that's part of the fun of seeing fictional characters, they are not real people so you can make up a story for them. I bet Reba is enough of a good actress to make up her own story about why her Dolly ended up in turn-of-the-century Yonkers.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
