Saw the broadway original several times, and to be fair, the show's biggest problem, despite its exciting score (and it is exciting) is in its curious lack of dramatic action.
Much of the story of Eva is shoved in our faces by Che's narrative -- not dramatized through individual scenes, ones that might let us make up our minds about this odd heroine. Che tells us what she did wrong, how ego-centric she is, etc., and we never get to experience her rise by observing her actions. It's all pre-packaged by Che (even "Goodnight and thank you" basically makes her a cheap whore from the top -- not a great way to get inside this woman.) We need to learn more about Eva via Eva -- not Che. But that material isn't in the text. Che is omnicient, and that cold, "Brechtian" approach may make for a strong political point of view, but it strips the story of much of its drama. This was painfully obvious in the film, when Madonna's Eva seemed to be less of a presence in every sequence, not more of one. It's a strange show -- so many wonderful tunes, a great subject, and seemingly a great role -- but a hollow, undramatized center.
