TotallyEffed's take is so useful at this late date, the comparison with Gleason's je ne sais quoi attributes informing her Baker's Wife the perfect illustration: some actors inhabit roles, creating an alchemy of character and artist that's impossible to frame with words. Acting is both a science - craft - and a mysterious art, the morphing into another via an almost chemical synergy. Here, we see a gifted musical comedy star tackling a role outside her resume's catalog, a woman who has no buried ingenue to excavate, a Chenoweth specialty. Arguably, Jackie is the opposite: she was always a tough broad, even as a teen. That seems to be what the Scott take delivers: this hardened creature who self-presents in guileless Barbie drag but cannot camouflage an inherent ruthlessness. Chenoweth may aim for that push-pull in the woman, yet we mostly see her effort. To Effed's point, the show doesn't succeed with Scott, but we do grasp the character being dramatized.
