Idina Menzel is unique, the musical not

I like Idina Menzel really like, and the musical was obviously written for her powerful voice. But it is precisely for this reason it seems to me the melody and dynamics, as well as the drafting of the secondary characters of the musical to come a little short. In short, despite the good initial idea to present the consequences of two seemingly banal choices, the question of profession or career, the concern for the goal of one's life cycle, the lack of Musical "pep". I particularly like, however, which is taken here not mince his words, but the musical in his story and his characters really 'unverschönt' looks like taken from real life. I suspect that someone who is better able to identify with the main character as I determined this musical could write a very different review. For me, the musical lacks the certain something.
