Throughout the show, I've gained a particular dislike for the character Ivy.
She initially gained the role of Marilyn in the musical, but she is unpleasant and rude, and in my opinion, tries to hard. She is talented, but her crave for fame is unhealthy. She's constantly having to be taken care of by others, and doesn't seem like she can handle the pressure of starring in a musical, while balancing taking care of herself.
The main character Karen, however, is much sweeter, as she's supposed to be.
She, however, doesn't seem to have quite found her voice and doesn't have as much confidence in her abilities. She too is talented, but she doesn't seem to "own" it. She doesn't have the same guts and confidence that Ivy has.
The show is very captivating and is great for anyone who loves music, dancing, and broadway. I definitely recommend it!
