I saw Dolly 3 times on Broadway with Midler, Donna Murphy, and Bernadette Peters. Beanie gave a delightful performance. Of course, I heard her laugh. I even chatted with her at the stage door. She was charming. She exuded enthusiasm. I think the show itself was one of the best revivals I've ever seen.
Maybe the show and her performance was not for you. No show is loved by everyone. However, many on this board (and I as well) feel that there is no need for mean spirited comments.
